DescriptionECHEMI Editorial ReferenceDimethyl sulfate is a colorless, oily liquid that is slightly soluble in water. It has a faint, onion-like odor; the odor threshold has not been established. The vapor pressure for dimethyl sulfate is 0.5 mm Hg at 20 °C, and it has a log octanol/water partition coefficient (log Kow ) of 0.032. Dimethyl sulfate is essentially odorless. The specific gravity of this colorless, corrosive, oily liquid is 1.3322 g/cm3. Dimethyl sulfate is soluble in ether, dioxane, acetone, benzene, and other aromati
Dimethyl sulfate is a chemical compound with formula (CH3O)2SO2. As the diester of methanol and sulfuric acid, its formula is often written as (CH3)2SO4 or even Me2SO4, where CH3 or Me is methyl. Me2SO4 is mainly used as a methylating agent in organic synthesis.CertificatesBasic Info-
