Dimethylcarbamoyl chloride is used as an intermediate in the production of pharmaceuticals, pesticides, and dyes. Acute (short-term) inhalation exposure to dimethylcarbamoyl chloride has been observed to result in damaged mucous membranes of the nose, throat, and lungs, and cause difficulty in breathing in rats. No information is available on the chronic (long-term), reproductive, developmental, or carcinogenic health effects of dimethylcarbamoyl chloride in humans. Nasal tract carcinomas have been observed in rats and male hamsters following inhalation exposure. EPA has not classified dimethylcarbamoyl chloride for potential carcinogenicity.
