About N,N-Dimethylacetamide
N,N-Dimethylacetamide (C4H9NO, DMA, DMAc) is a colorless, high boiling point, polar aprotic solvent with a faint amine-like odor. It is widely used in organic synthesis and industrial applications due to its ability to dissolve a wide range of polymers and resins. DMAc is commonly employed in the production of acrylic fibers, plastics, films, coatings, and in the spinning of polyurethane-based fibers. It is miscible with water and most organic solvents, making it a versatile solvent in chemical reactions and processes. Chemical formula: CH3CON(CH3)2
