	     You were mighty close with mercaptoethanol!  The actual compound is
methylmercaptan, and yes, it is sulfur based.  Nasty stuff indeed in pure
form, if you are ever anywhere near it.  As bad as skunks smell, they do
not produce a pure form.  By the way, it technically is not their urine
that stinks.  They have specialized oil glands around their anus, that are
contractile.  That is where they spray their "odor-bombs" from.
