Mercaptan

Mercaptan
Mercaptan Mer*cap"tan, n. [F., fr. NL. mercurius mercury + L. captans, p. pr. of captare to seize, v. intens. fr. capere.] (Chem.) Any one of series of compounds having an {-SH} radical attached to a carbon atom, also considered as hydrosulphides of alcohol radicals, in composition resembling the alcohols, but containing sulphur in place of oxygen, and hence called also the {sulphur alcohols}. In general, they are colorless liquids having a strong, repulsive, garlic odor. The name is specifically applied to ethyl mercaptan, {C2H5SH}. So called from its avidity for mercury, and other metals. [1913 Webster]
