Isopropyl mercaptan is a thiol with the formula C3H8S. It is a water-white[clarification needed] liquid with an extremely pungent odor resembling skunk spray or rotten eggs. The pungent smell allows it to be used as an odorizer.[2] The FDA has approved it for use as a food additive for its flavor.[3] Another use is as a rubber additive.[4]
