Dimethyl sulfate on the central nervous system excitement before inhibitory role of, if anyone in the concentration of 500 mg/m for 10 minutes to death. Dimethyl sulfate ester of methanol, sulfuric acid and the hydrolysis of intermediate products of methyl hydrogen sulfate can cause systemic poisoning. Dimethyl sulfate has strong corrosive to eye, upper respiratory tract and skin, it can cause conjunctiva hyperemia and edema, Epithelial Defects, so that part of trachea and bronchial epithelial cell necrosis, resulting in mediastinum or subcutaneous emphysema. In addition, after contact with skin can cause burns, blisters and depth of necrosis, contact allergic dermatitis.
