5-Amino-1MQ is a small molecule rather than a peptide — a quinolinium salt, and one of the handful of non-peptide compounds Vestrand keeps alongside its peptide catalog.
We stock it as a single laboratory lot and have each batch characterized by an independent lab, then post the certificate to its verification page so the purity on the label is something you can look up yourself.
The detail most people get wrong is the color. This is not a white powder; the documented material ranges from faint red to dark brown. It is also handled as a salt rather than a free base, which is simply how a charged small molecule like this is isolated.
