Dimethyl sulfate is a chemical compound with formula (CH 3 O) 2 SO 2. As the dimethyl ester of sulfuric acid. Its formula is often written as (CH 3) 2 SO 4 or even Me 2 SO 4; where CH 3 or Me is methyl. Me 2 SO 4 is mainly used as a methylating agent in organic synthesis.

Dimethyl sulfate is a colorless oily liquid, odorless to a faint onion-like odor. It is very toxic by inhalation. It is a combustible liquid and has a flash point of 182°F. It is slightly soluble in water and decomposed by water to give sulfuric acid with evolution of heat. It is corrosive to metals and tissue. It is a potent methylating agent.
