Methanedithiol is an organosulfur compound with the formula H2C(SH)2. A seldom used chemical, it forms when formaldehyde reacts with hydrogen sulfide under pressure:

CH2O + 2 H2S → H2C(SH)2 + H2O

This reaction competes with formation of trithiane:

3 H2C(SH)2 → [H2CS]3 + 3 H2S

Methanedithiol forms a solid dibenzoate derivative upon treatment with benzoic anhydride:

3 H2C(SH)2 + 2 (C6H5CO)2O → H2C[SC(O)C6H5]2 + 2 C6H5CO2H

Methanetrithiol is also known.
