What is 5-Amino-1MQ?
5-Amino-1MQ is a small-molecule quinolinium compound: a quinoline ring carrying a methyl group on its ring nitrogen and an amino group at position 5. It is catalogued under CAS 685079-15-6 and PubChem CID 950107, with the molecular formula C10H11N2+ and a molecular weight of 159.21 g/mol.1
The PubChem record describes the positively charged quinolinium ion. The salt form and counter-ion of the solid are not specified, and lot identity is confirmed on the Certificate of Analysis.3
The material described on this page is intended as a laboratory reagent.
Handling
5-Amino-1MQ is a dry solid as received in the laboratory. A reference supplier lists storage of this compound as a solid at -20 °C.2
- Allow the sealed container to reach room temperature before opening, so moisture does not condense on the solid.
- Keep the solid dry, sealed and away from bright light.
- Avoid repeated freezing and thawing.
Storage and stability
| State | Temperature | Notes |
|---|---|---|
| Dry, sealed | -20 °C2 | Keep dry and away from bright light. |
| Freezing and thawing | Avoid repeated freezing and thawing | Applies to the dry solid. |
How each lot is tested
Each lot in the My Oasis Labs Peptides catalogue is tested by an independent third-party laboratory.3 The 5-Amino-1MQ certificate page names the testing laboratories and lists each lot's purity, net content and test date. Three measurements are reported.
Identity
Mass spectrometry
Checks that the measured molecular mass matches 5-Amino-1MQ. The calculated monoisotopic mass is 159.09 Da.1
A matching mass is consistent with the expected composition. It does not by itself confirm the structure.
Purity
High-performance liquid chromatography (HPLC)
Separates the material from synthesis-related impurities. Purity is reported as the main peak's share of the total detected signal.
Reported per lot. The Oasis Labs specification is 99% or greater.
Quantity
Net content
Measures the mass of material actually present in the sample tested.
Reported per lot on the Certificate of Analysis.
Technical notes
What does the Certificate of Analysis confirm?
Identity by mass spectrometry, purity by HPLC, and the net content of the sample.
Why is the material freeze-dried?
Dry solids are generally more stable than solutions. The material is lyophilized and kept sealed until use in the laboratory.
5-Amino-1MQ lot certificates
Each listed 5-Amino-1MQ lot has its own certificate covering identity, purity and net content.
