Safety information
N,N-Dimethylacetamide (DMAc) is a hazardous industrial solvent that is toxic, flammable, and poses significant risks to reproductive health and the liver.
Health Hazards
DMAc is reproductively toxic; repeated exposure can lead to liver damage. It also suppresses the central nervous system, potentially causing dizziness, drowsiness, and hallucinations. It is readily absorbed through skin contact, inhalation, and ingestion. As a flammable liquid, it causes severe eye irritation; occupational exposure concentrations should be controlled below 10 ppm TWA. Appropriate personal protective equipment, including butyl rubber gloves, splash-proof goggles, and necessary respiratory protection, must be worn during handling.
Handling and Storage
To avoid flammability, N,N-Dimethylacetamide (CAS 127-19-5) should be kept away from heat, sparks, and open flames. DMAc chemicals should be stored in a cool, well-ventilated, and locked area. Professional handling training is required before use.
