5-Amino-1MQ Iodide vs. Chloride: Why Can Salt Names, CAS Labels, and Active-Compound Mass Point to Different Specifications?
In this article
In the rapidly advancing field of peptide and small-molecule research, precision is everything. Recently, a critical discussion surfaced in online research communities (such as Reddit’s r/PeptidePathways) regarding 5-Amino-1MQ, a popular NNMT (Nicotinamide N-methyltransferase) inhibitor. Researchers and buyers noted a significant discrepancy: 5-Amino-1MQ is commonly available in two different salt forms—Iodide and Chloride—yet both are frequently sold under the exact same CAS number (42464-96-0).
For clinic owners, researchers, and resellers, this lack of transparency creates a major problem. If salt names, CAS labels, and molecular weights point to different specifications, how do you know what you are actually buying?
As a brand dedicated to providing Precision Analytical Compounds for Cellular Assays, Corapep is here to break down the chemistry, explain the active-compound mass differences, and show you how to ensure you get exactly what your research demands.
The Chemistry: Iodide vs. Chloride Salt Forms
When synthesizing compounds like 5-Amino-1MQ for stability and solubility, the active "base" molecule is often paired with an acid to create a salt. The two most common salts for 5-Amino-1MQ are the iodide salt and the chloride salt.
1. The Molecular Weight Dilemma
The core issue lies in the atomic weight of the counterions used in the salt forms:
- Iodine (I) is a large, heavy atom with an atomic mass of roughly 126.9 g/mol.
- Chlorine (Cl) is much lighter, with an atomic mass of roughly 35.45 g/mol.
Because the iodide ion is significantly heavier than the chloride ion, 5-Amino-1MQ Iodide has a higher total molecular weight than 5-Amino-1MQ Chloride.
2. Active Compound Mass: Are You Getting Less per mg?
This difference in molecular weight directly impacts the amount of the active base compound you receive per milligram of powder.
If you measure out 10mg of 5-Amino-1MQ Iodide, a larger percentage of that 10mg is taken up by the heavy iodide ion. If you measure out 10mg of 5-Amino-1MQ Chloride, less weight is taken up by the chloride ion, meaning you yield a higher net mass of the actual active 5-Amino-1MQ molecule.
As noted by astute buyers, purchasing the Iodide form technically means you are getting less of the active compound per milligram compared to the Chloride form. For precision cellular assays or calculating exact dosing equivalents, this variance must be accounted for.
The CAS Number Confusion: 42464-96-0
Why is it so hard to differentiate these forms when purchasing?
In many supplier catalogs, both the Iodide and Chloride versions are listed under a single generic CAS number: 42464-96-0. Historically, this CAS number has been used broadly in the industry to refer to the 5-Amino-1MQ compound family, rather than a specific, highly defined salt form.
When vendors rely solely on a generic CAS label without providing a detailed Certificate of Analysis (COA) or specifying the exact molecular weight, researchers are left guessing which salt they are receiving. This can compromise experimental reproducibility and formulation accuracy.
Summary: Core Questions & Answers for Researchers
(Quick-Reference)
- What is the difference between 5-Amino-1MQ Iodide and Chloride?
The primary difference is the salt counterion. The Iodide form has a higher molecular weight due to the heavy iodine atom, while the Chloride form is lighter.
- Which 5-Amino-1MQ salt yields more active compound?
Because chloride is lighter than iodide, 5-Amino-1MQ Chloride contains a higher mass percentage of the active base molecule per milligram of total powder.
- Why do both forms use CAS 42464-96-0?
Many suppliers use this CAS number generically for the 5-Amino-1MQ base or general salts, causing confusion. Precise identification requires examining the exact molecular weight and chemical structure on a batch-specific COA.
