Rather interesting article in which I find out that TCA has no smell:

A rather interesting, if surprising, article.

I have a sample of a few crystals of TCA, compliments of a friend at ScottLabs, that is soaking in vodka. The small jar
is enclosed in two ZipLok, placed in a jar that has a tight clamp on the top, w/ a piece of SaranWrap sealing the
opening. Yet I can pick up the jar, thru all the seals, and smell the musty/wet newspapers when I hold it close
to my nose. Wonder what actual thing I'm smelling that the TCA is subducting?

Anyway, a nice read for the chemists on the Board.
