AI overview
A thiol is a type of organic compound that contains a sulfur atom bonded to a hydrogen atom, giving it unique chemical properties. Thiols are important in biological systems and industrial chemistry because this sulfur-hydrogen group makes them reactive and useful for various chemical processes and functions in living organisms.

In organic chemistry, a thiol (; ), or thiol derivative, is any organosulfur compound of the form , where R represents an alkyl or other organic substituent. The 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".
