Thiol vs. Thiolate — What's the Difference?

A thiol () 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.

(chemistry) any derivative of a thiol in which a metal atom replaces the hydrogen attached to sulfur RSH => RS^-M⁺

An organic compound containing the group —SH, i.e. a sulphur-containing analogue of an alcohol.

A sulfur-containing organic compound with the general formula RSH where R is any hydrocarbon group. Also called mercaptan.

(organic chemistry) A univalent organic radical (-SH) containing a sulphur and a hydrogen atom; a compound containing such a radical.
