5-Amino-1MQ from 5-Amino-1MQ Research Supply is a small-molecule quinolinium compound, supplied as a lyophilized powder in 50 mg vials. Every lot is independently tested, and its results are published as a lot record with the certificate PDF.

Specifications and current testing status in one place.
5-Amino-1MQ is a small molecule rather than a peptide, so the checks are simpler but the same in kind: is it the named compound, how pure is it, how much is in the vial. For lot KB-09573, ILS Laboratories reported 99.86% HPLC purity, identity confirmed against a 5-amino-1MQ reference standard, and 52.24 mg in a 50 mg vial, fentanyl not detected.
It is sold in 50 mg vials at $43.99, with a 10-vial researcher pack, through Klow.bio. One detail to note when buying: the certificate does not state the salt form, so weights here are given for the 5-amino-1-methylquinolinium cation.
Because the molecule is a cation, it is always supplied as a salt with a counterion, commonly iodide (C10H11IN2, 286.11 g/mol). The certificate does not state the counterion, so the formula and weight shown here are for the cation itself.
The quinolinium ring is planar and strongly UV-absorbing, which suits HPLC-UV purity analysis. The positive charge is fixed on the ring nitrogen and does not depend on pH; the 5-amino group is a weak base.

Store sealed, dry and protected from light at the temperature stated on the vial label. Allow a cold vial to reach room temperature before opening. Lyophilized material absorbs moisture from the air, and absorbed moisture restarts the reactions that drying slows, so keep vials sealed until needed. Storage and stability guide.

All testing is performed by ILS Laboratories, an independent laboratory, on every lot.
Reversed-phase high-performance liquid chromatography separates the sample's components by hydrophobicity, and a UV detector records each as a peak. Purity is the main peak's area as a percentage of all detected peak area.
Limits: does not identify the peak, and impurities that co-elute or absorb weakly in UV can be under-counted. More on HPLC
The laboratory runs the sample and a reference standard of 5-Amino-1MQ under the same chromatographic conditions. Identity is reported as confirmed when the sample’s main peak elutes at the reference standard’s retention time.
Limits: a retention-time match is consistent with the named compound but is not a mass or structure measurement; compounds with similar retention can co-elute. More on HPLC
The laboratory screens each lot by immunoassay at the cutoff printed on the certificate. Current lots are reported as not detected.
Limits: a negative result means below the cutoff for the sample tested; an immunoassay screens for its target only.
The laboratory quantifies the main compound in the tested vial against a standard. It is reported in milligrams next to the labeled vial size.
Limits: measured on the vial tested; other vials from the same lot are expected to be similar but are not individually measured.

HPLC-UV purity for each current lot.
5-Amino-1MQ is a small-molecule quinolinium compound. 5-Amino-1MQ Research Supply supplies it as a lyophilized powder in 50 mg vials, with an independent certificate of analysis for every lot.
5-Amino-1MQ research material is 5-Amino-1MQ supplied for laboratory research, sold by lot, with each lot's identity, purity and net content documented by an independent laboratory in a published certificate of analysis.
Because the molecule is a cation, it is always supplied as a salt with a counterion, commonly iodide (C10H11IN2, 286.11 g/mol). The certificate does not state the counterion, so the formula and weight shown here are for the cation itself.
The molecular formula (5-amino-1-methylquinolinium cation) is C10H11N2 and the average molecular weight is 159.21 g/mol.
