2,4-Dithiapentane is an organosulfur compound. It is a colorless liquid with a strong odor.
2,4-Dithiapentane is the dimethyldithioacetal of formaldehyde. It is prepared by the acid-catalyzed addition of methyl mercaptan, the main aromatic compound in both halitosis and foot odor and a secondary compound in flatulence, to formaldehyde.
- 2 CH3SH + H2C=O → CH3SCH2SCH3 + H2O
2,4-Dithiapentane is found as an aromatic component in some truffle varietals. A synthetic version is used as the primary aromatic additive in truffle oil. It has also been found to occur naturally in rotting wood of some species in genus Lecythis.
