About C3H7NO (Dimethylformamide, DMF)

N,N-Dimethylformamide (C₃H₇NO, DMF) 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 compounds. DMF is commonly employed in the production of acrylic fibers, plastics, pesticides, and as a solvent in peptide coupling for pharmaceuticals. It is miscible with water and most organic liquids, making it a versatile solvent in chemical reactions and processes. Chemical formula: HCON(CH₃)₂

Other names: C3H7NO, Dimethylformamide, DMF, N,N-Dimethylformamide, C₃H₇NO, DMF, N,N-Dimethylmethanamide, Formyldimethylamine, Dimethylformalin
