Thiol In organic chemistry, a thiol is an organosulfur compound that contains a carbon-bonded sulfhydryl group. Thiols are the sulfur analogue of alcohols, and the word is a portmanteau of thion + alcohol, with the first word deriving from Greek Î¸Îµá¿Î¿Î½ = sulfur. The âSH functional group itself is referred to as either a thiol group or a sulfhydryl group. Many thiols have strong odors resembling that of garlic.
The thiol functional group is similar to the hydroxyl group except the oxygen atom in the hydroxyl group is a sulfur atom in the thiol group. Thiol functional group is also known as a sulfhydryl functional group. Thiol functional groups have formula -SH. Molecules that contain thiol groups are also called mercaptans.
