Isopropyl mercaptan is an organic compound with the formula C3H8S. It has the CAS Registry Number 75-33-2.[2] It is REACH registered with the European number of 200-861-4.[3] It is a water-white liquid with an extremely pungent odor resembling skunk spray or bad eggs. The odor means one use is as an odorizer.[4] Despite this, it has Food and Drug Administration sanction as a food additive to add flavor.[5] Another use is as a rubber additive.[6]
Analysis and detection
The usual method of analysis and detection is by gas chromatography.[7][8]
