Hazardous Substances Data: 79-16-3(Hazardous Substances Data)
N-Methylacetamide (CAS NO.79-16-3) is also named as AI3-18019 ; Acetamide, N-methyl- ; Acetamide, methyl- ; Acetic acid, amide, N-methyl ; HSDB 94 ; Methylacetamide ; Monomethylacetamide ; N-Methylacetamide ; N-Monomethylacetamide ; NSC 747 ; X 44 . N-Methylacetamide (CAS NO.79-16-3) is colourless liquid or solid. It is stable and combustible but incompatible with strong oxidizing agents. It is toxic. It is flammable. It will produce toxic nitrogen oxide fumes when buring. So the storage environment should be ventilate, low-temperature and dry.
