Sergey-
Piperidine is a precursor for an illicit drug; I believe it
is phencyclidine. It is a major nuisance to buy it in the US as
well. We have one person in our purchasing department who is the
ONLY person on campus who may order such so-called controlled
substances. Methylamine hydrochloride, recommended for scavenging
the traces of cyanate in urea, is another case- precursor of
methamphetamine. For the methylamine it is easy to switch to
ethylamine.
I have wondered about the feasibility of switching to
N-methylpiperidine, which must be of similar basicity and was used as
the coupling base in HP protein sequencers. However, I didn't think
we should switch because with extra trouble we can order piperidine.
