thymosin — 16 things I got wrong before I got it right
thymosin — 16 things I got wrong before I got it right. Not a hot take, just something I have not seen said plainly here.
Asked for identity confirmation on an unusual line and got a mass spectrum with the theoretical mass alongside. That is the answer I now look for everywhere.
Stocked lines and made-to-order lines have different lead times and different storage histories. Both are ordinary; the difference is worth confirming before you commit.
Storage guidance that names a temperature, a state and a duration reflects actual stability work. Generic guidance usually reflects a template.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.
best — the order this archive was captured in
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.
Has anyone here tested that compound at all?
catalogue depth is not the same as catalogue quality
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.
Has anyone here tested that compound at all?
This is the rule for anything unusual. Identity before anything else.
Cosigning the lead-time point. Made-to-order and stocked are completely different propositions and both are legitimate.
That method was developed for a different compound class and would not resolve the impurities you are asking about.
