Grapefruit mercaptan is the common name for a natural organic compound found in grapefruit. It is a monoterpenoid that contains a thiol (aka mercaptan) functional group. Structurally a hydroxy group of terpineol is replaced by the thiol in grapefruit mercaptan so it also called thioterpineol. Volatile thiols typically have very strong often unpleasant odors that can be detected by humans in very low concentrations.
