Methanedithiol is an organosulfur compound with the formula H2C(SH)2. A seldom used chemical, it form when formaldehyde reacts with hydrogen sulfide under pressure:
This reaction competes with formation of trithiane:
Methanedithiol forms a solid dibenzoate derivative upon treatment with benzoic anhydride:[1]
Methanetrithiol is also known.
