Dimethylformamide Testing

Dimethylformamide (DMFa) is a widely used aprotic polar solvent. It can be used not only as a dye solvent, a sizing agent for polyurethane, polyacrylonitrile, and polyvinyl chloride, a paint stripper for removing paint, but also for the synthesis of high - efficiency and low - toxicity pesticides and insecticides, the synthesis of pharmaceutical intermediates, the quenching of tinned parts, and the cleaning of circuit boards. However, DMF is classified as a substance with reproductive toxicity, acute toxicity, and eye - irritating properties according to the CLP regulation, and was included in the SVHC list by the end of 2012. In October 2018, Italy proposed to the ECHA to restrict the market placement and use of DMFa. After evaluation, the ECHA committee submitted its opinions to the European Commission. The European Commission, after comprehensively considering the proposal and the opinions of the ECHA committee, believed that the risks to workers exposed to N,N - dimethylformamide above specific DNEL values were unacceptable, and the proposed restrictive clauses were the most suitable measures to address this risk at present.
