Thiol

A thiol (/ˈθaɪɒl/) or thiol derivative is any organosulfur compound of the form R−SH, where R represents an alkyl or other organic substituent. The –SH functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. 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 blend of "thio-" with "alcohol", where the first word deriving from Greek θεῖον (theion) meaning "sulfur".
