Dimethylacetamide, fully named N,N-Dimethylacetamide, chemical formula: CH3C(O)N(CH3)2, abbreviated as DMAC or DMA, molecular weight 87.12 g/mol^[1]. It is commonly used as an aprotic polar solvent. It is a colorless transparent liquid, flammable. It can mix freely with water, alcohols, ethers, esters, benzene, aromatic compounds, and other organic solvents, and can activate compound molecules, thus widely used as a solvent and catalyst.
