In organic chemistry, a thiol is a organosulfur compound that contains a carbon-bonded sulfhydryl (-C-SH or R-SH) group (where R represents an alkane, alkene, or other carbon-containing group of atoms). Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl group of an alcohol), and the word is a portmanteau of "thio" + "alcohol," with the first word deriving from Greek θεῖον ("thion") = "sulfur". The -SH functional group itself is referred to as either a thiol group or a sulfhydryl group.
