Mercapto group is a functional group in organic chemistry with the general formula R-SH. It consists of a sulfur atom bonded to a hydrogen atom and an alkyl or aryl group. The mercapto group is also known as a thiol group or sulfhydryl group. Thiols are the sulfur analogs of alcohols, where the oxygen atom is replaced by a sulfur atom.

Mercapto groups exhibit reactivity similar to hydroxyl groups in alcohols, but with some key differences due
