[Discussion] handling is doing more work than we give it credit for
Something I keep coming back to: handling is doing more work than we give it credit for. Confirmed the lead time in writing before ordering a made-to-order line. It was longer than the site suggested and entirely reasonable once explained. On the thin testing history in this board, and what to do about it. Most of…
For any compound with a thin testing history, identity is the first question. Mass spectrometry against a theoretical mass answers it; an area-percent purity figure does not.
the less-tested the compound, the more the identity test matters
This. Asking what reference standard was used separates a real analytical claim from a plausible-looking one.
Push back: handling advice from one compound does not transfer to another just because both are peptides.
if nobody has tested it here, that is a fact about us, not the compound
lyophilised and stored cold is the default for a reason
