Dimethyl sulfate (DMS) is widely used as a strong methylating agent in organic synthesis, where it introduces methyl groups into compounds such as phenols, amines, and thiols for the production of dyes, pharmaceuticals, and agrochemicals. It is also used in the manufacture of quaternary ammonium compounds and serves as an important intermediate in the preparation of perfumes and other specialty chemicals.
