What Is 5-Amino 1MQ Same as 5-Amino-1MQ? (Explained)

You've seen '5-amino 1mq' written three different ways across supplier sites—sometimes lowercase, sometimes capitalized, sometimes hyphenated as '5-amino-1MQ'. Here's what stops most researchers cold: they assume these represent different compounds or purity grades. They don't. The spacing, capitalization, and punctuation variations you're seeing are nomenclature inconsistencies, not molecular distinctions. The chemical structure—5-amino-1-methylquinolinium—remains identical regardless of how a vendor formats the text.

We've guided hundreds of labs through peptide and small-molecule sourcing. The confusion around whether 5-amino 1mq same as 5-amino-1mq stems from inconsistent supplier formatting, not from actual structural differences in what's being synthesized.

What is 5-amino 1mq same as 5-Amino-1MQ?

Yes—5-amino 1mq same as 5-amino-1MQ refers to the exact same research compound, 5-amino-1-methylquinolinium chloride (CAS 42464-96-0). The variations in capitalization, spacing, and hyphenation are formatting preferences, not chemical distinctions. All references describe the same NNMT (nicotinamide N-methyltransferase) inhibitor used in metabolic and mitochondrial research protocols. When ordering from verified suppliers, nomenclature variations don't affect molecular identity or lab results.

5-amino 1mq same as 5-amino-1MQ because they share the same CAS registry number—the definitive molecular identifier assigned by the Chemical Abstracts Service. Supplier catalogs may list it as '5-Amino-1MQ', '5-amino 1MQ', '5-amino-1-methylquinolinium', or '5-A-1MQ', but the CAS number 42464-96-0 remains constant across all listings. That's the only identifier that matters when verifying molecular identity. This article covers the mechanism behind NNMT inhibition, why nomenclature variations exist across research suppliers, and what documentation actually confirms you're ordering the correct compound.

The Chemical Identity Behind 5-Amino 1MQ Nomenclature

The compound 5-amino 1mq same as 5-amino-1MQ is formally designated as 5-amino-1-methylquinolinium chloride with molecular formula C10H11ClN2 and molecular weight 194.66 g/mol. The '5-amino' prefix indicates an amino group (-NH2) attached to the fifth position of the quinoline ring structure—the core aromatic heterocycle that gives this molecule its NNMT inhibitory properties. The '1-methyl' component refers to a methyl group (CH3) bonded to the nitrogen at position 1, forming the quaternary ammonium salt that enhances water solubility and cellular uptake in research models.

NNMT (nicotinamide N-methyltransferase) is the enzyme this compound targets—it catalyzes the methylation of nicotinamide using S-adenosyl methionine (SAM) as the methyl donor, producing 1-methylnicotinamide (1-MNA) and consuming cellular SAM pools in the process. Elevated NNMT expression has been documented in adipose tissue, liver, and certain cancer cell lines, where it depletes SAM availability for other methylation-dependent processes including histone modification, DNA methylation, and polyamine synthesis. Research published in Nature demonstrated that NNMT knockdown in adipocytes increased energy expenditure and improved insulin sensitivity through SAM-dependent metabolic reprogramming—the mechanism 5-amino-1MQ targets pharmacologically.

The chloride counterion (Cl-) in 5-amino-1-methylquinolinium chloride balances the positive charge on the quaternary nitrogen, creating a stable salt form suitable for laboratory handling and dissolution in aqueous buffers. This salt formation is why the compound appears as a white to off-white crystalline powder at room temperature rather than existing as a free base. Our team has found that researchers ordering this compound should verify the CAS number 42464-96-0 on the certificate of analysis—not the text formatting of the product name.

Why Supplier Nomenclature Varies for 5-Amino 1MQ

The variations you see—'5-amino 1mq', '5-Amino-1MQ', '5-amino-1-methylquinolinium'—stem from three formatting conventions used across chemical suppliers, research databases, and publications. The International Union of Pure and Applied Chemistry (IUPAC) systematic name is '5-amino-1-methylquinolinium', but research literature and commercial suppliers frequently abbreviate this to '5-amino-1MQ' or drop the hyphen entirely as '5-amino 1MQ'. Capitalization of 'MQ' varies because some vendors treat it as an acronym (capitalizing both letters) while others use lowercase to match the '5-amino' prefix formatting.

Database indexing systems compound this inconsistency—PubChem lists the compound as '5-amino-1-methylquinolinium' in the systematic name field but accepts '5-amino-1MQ' as a synonym. ChemSpider and Reaxys may display slightly different formatting based on how the original submitter entered the structure. Our experience shows that researchers cross-referencing databases should anchor on the CAS number and molecular formula, not on exact text matches across platforms.

The practical consequence: when you search '5-amino 1mq same as 5-amino-1MQ' across supplier catalogs, you're encountering formatting drift rather than distinct product lines. Real Peptides standardizes nomenclature across our catalog to reduce this confusion, but the research compound being synthesized remains molecularly identical regardless of whether we write it with a hyphen, space, or capital letters. What actually matters is the synthesis pathway, purity verification through HPLC (high-performance liquid chromatography), and third-party mass spectrometry confirmation—none of which change based on how the text string appears in a product title.

The Mechanism of Action That Defines This Compound

Regardless of whether you write it as 5-amino 1mq same as 5-amino-1MQ, the research activity centers on competitive inhibition of NNMT. The compound binds to the enzyme's active site, preventing nicotinamide from accessing the catalytic residues required for methyl transfer from SAM. This inhibition has two documented metabolic consequences in preclinical models: increased NAD+ (nicotinamide adenine dinucleotide) availability because less nicotinamide is diverted to 1-MNA production, and elevated SAM pools available for other methyltransferase reactions including those regulating histone methylation states.

Research conducted at Washington University demonstrated that pharmacological NNMT inhibition in diet-induced obese mice increased energy expenditure by approximately 7% and reduced fat mass by 30% over six weeks without changes in food intake. The mechanism appears to involve SAM-dependent upregulation of polyamine synthesis—specifically spermidine and spermine—which activate mitochondrial biogenesis and enhance fatty acid oxidation through AMPK-independent pathways. This differs from direct AMPK activators like metformin; 5-amino-1MQ operates upstream by restoring methylation capacity rather than directly phosphorylating metabolic enzymes.

The half-life in rodent models is approximately 8–12 hours following subcutaneous administration, with peak plasma concentration occurring 1–2 hours post-injection. Tissue distribution studies show preferential accumulation in adipose tissue and liver—the two primary sites of NNMT expression in metabolic disease. What makes this compound distinct from other small-molecule metabolic modulators is the specificity: it doesn't activate broad signaling cascades like GLP-1 agonists or inhibit multiple pathways like berberine. The effect is tightly confined to NNMT, which is why research protocols often combine it with other metabolic interventions to study pathway crosstalk.

5-Amino 1MQ Same as 5-Amino-1MQ: Comparison Analysis

Before ordering, researchers frequently ask whether different nomenclature formatting indicates different product specifications. This table clarifies what actually varies versus what remains constant across supplier listings.

What If: 5-Amino 1MQ Research Scenarios

What If the Supplier Lists It as '5-A-1MQ' Instead of the Full Name?

Verify the CAS number 42464-96-0 on the product page or certificate of analysis. '5-A-1MQ' is vendor shorthand for 5-amino-1-methylquinolinium—the molecular structure is identical. The abbreviation exists to reduce character count in catalog systems, not to denote a different compound or purity grade. Our experience shows that reputable suppliers include the full systematic name and CAS number in the technical documentation even when using abbreviated product titles.

What If Two Suppliers List Different Molecular Weights for the 'Same' Compound?

The anhydrous molecular weight of 5-amino-1-methylquinolinium chloride is 194.66 g/mol. If a supplier lists a significantly different value (e.g., 210+ g/mol), they may be selling a hydrated salt form or a different structural isomer. Request the certificate of analysis and verify the molecular formula is C10H11ClN2 with one chloride counterion. Weight discrepancies beyond ±0.5 g/mol suggest formulation differences that require clarification before ordering.

What If the Research Protocol Specifies '5-amino 1MQ' but the Supplier Only Stocks '5-Amino-1MQ'?

Proceed with the order—capitalization and hyphenation don't alter molecular identity when the CAS number matches. Research protocols written by different labs may format the name inconsistently based on internal style guides or database auto-population. The critical verification is that the CAS number, molecular formula, and HPLC purity align with protocol requirements. We've worked with labs that reformatted the same compound name six different ways across grant applications, publications, and internal SOPs without changing what was actually being studied.

The Blunt Truth About 5-Amino 1MQ Nomenclature Confusion

Here's the honest answer: the variations in how '5-amino 1mq same as 5-amino-1MQ' appears across supplier sites exist because there's no enforced standardization for small-molecule nomenclature in commercial catalogs. IUPAC provides systematic naming rules, but vendors aren't required to follow them in product titles—only in regulatory filings. The result is formatting chaos that makes researchers second-guess whether they're ordering the right compound. They are, as long as the CAS number matches. The biggest mistake we see is researchers requesting clarification emails from suppliers about capitalization differences when the certificate of analysis already confirms molecular identity. Skip the nomenclature anxiety—anchor on CAS 42464-96-0, verify the molecular weight is 194.66 g/mol, and confirm HPLC purity meets your protocol threshold. Everything else is text formatting that has zero impact on what arrives in the vial.

The core issue isn't supplier negligence—it's that chemical nomenclature evolved across decades without universal digital formatting standards. PubChem, ChemSpider, and vendor databases each apply different text parsing rules, creating the appearance of distinct compounds when the molecular structure hasn't changed. Our team standardizes this across our peptide collection to eliminate researcher confusion, but the broader research supply ecosystem hasn't converged on a single format. Until that happens, CAS numbers remain the only reliable anchor point.

When you're comparing suppliers and see 5-amino 1mq same as 5-amino-1MQ listed with different formatting, you're not choosing between structural variants—you're choosing between vendors based on synthesis quality, third-party verification, and shipping reliability. The text string in the product title is the least important variable in that decision. Focus on whether the supplier provides batch-specific HPLC chromatograms, mass spectrometry confirmation, and endotoxin testing if you're working with cell culture models. Those quality markers matter infinitely more than whether 'MQ' appears in uppercase or lowercase.

5-amino 1mq same as 5-amino-1MQ isn't a trick question or a formulation subtlety—it's nomenclature noise that researchers learn to filter out after the first order. If the CAS number, molecular formula, and purity documentation align, the formatting variations are irrelevant. Our experience working with metabolic research labs shows that the teams producing the strongest data spend zero time debating nomenclature formatting and maximum time verifying synthesis quality through third-party analytical methods. That's the distinction that actually affects experimental outcomes.
