dimetilszulfát

Dimethyl sulfate is a chemical compound with the formula (CH3O)2SO2. It is a colorless, oily liquid with a faint onion-like odor, although it is often odorless in pure form. Dimethyl sulfate is a potent alkylating agent, meaning it readily transfers methyl groups to other molecules. This reactivity makes it a valuable reagent in organic synthesis and industrial processes.

It is commonly used in the production of dyes, perfumes, pharmaceuticals, and pesticides. Its ability to methylate various functional groups, such as hydroxyl, amino, and thiol groups, is central to its applications. For example, it can be used to convert alcohols into methyl ethers or amines into N-methylated derivatives. In the pharmaceutical industry, it plays a role in the synthesis of certain drug intermediates.

Despite its utility, dimethyl sulfate is highly toxic and corrosive. Exposure can cause severe burns to skin and eyes, and inhalation of its vapors can lead to respiratory irritation and damage, potentially with delayed effects. Due to its hazardous nature, strict safety precautions, including proper ventilation and personal protective equipment, are essential when handling this chemical. It is classified as a probable human carcinogen.
