[Question] how do you actually verify TB-500
Slightly embarrassed to be asking this, but: how do you actually verify TB-500. Purity methods differ by compound class. A gradient and wavelength developed for one peptide will not necessarily resolve the relevant impurities of another. Storage guidance that names a temperature, a state and a duration reflects…
That result is an area percent from an unspecified method, which is not the same as the identity confirmation being discussed.
ask what the reference standard was
net peptide content is where the surprises live
if nobody has tested it here, that is a fact about us, not the compound
[removed by moderator]
lyophilised and stored cold is the default for a reason
Agreed that thin testing here says something about the members, not about the material.

Disagreeing with this bit: handling for one compound does not transfer to another by default.
Naming in this space is inconsistent. Several widely used names map to more than one molecule, so a catalogue number and a sequence beat a common name every time.
