Dimethyl sulfate is a powerful methylating agent used extensively in organic synthesis to transfer methyl groups to oxygen, nitrogen, and sulfur atoms. This colorless, oily liquid is highly toxic and poses significant health risks, including carcinogenic and mutagenic potential. In the chemical industry, it’s employed in the production of dyes, perfumes, pharmaceuticals, and pesticides. Due to its hazardous nature, its use requires stringent safety measures to prevent exposure through inhalation, ingestion, or skin contact.
