Pharmaceutical N-Dimethylacetamide with CAS No. 127-19-5
N,N-Dimethylacetamide, also known as Acetyl Dimethylamine, Acetyldimethylamine, or DMAC for short, is an aprotic, highly polar solvent with a slight ammonia odor and a strong dissolving power. It is widely used as a solvent and catalyst because it can be freely miscible with water, aromatic compounds, esters, ketones, alcohols, ethers, benzene, and chloroform, and can activate molecules of compounds. As a solvent with high boiling point, high flash point, high thermal stability, and chemical stability, it can be used for drawing solvent for polyacrylonitrile, synthetic resins and natural resins, vinyl formate, vinyl pyridine and other aromatic hydrocarbons. Carboxylic acid solvent; catalyst can be used for urea heating cyanuric acid, alkyl halides and metal cyanide reaction nitrile, sodium acetylene and halogenated alkyl reaction alkyl alkyne, organic halides and cyanate reaction isocyanate and other processes. N,N-dimethylacetamide can also be used as a solvent for electrolysis solvents and photographic couplers, as a depainting agent, a raw material for organic synthesis, a pesticide, and a pharmaceutical raw material. Separation of styrene extractive distillation solvent from the C8 fraction.
