Properties: A transparent liquid
Uses: Common solvents for chemical reactions

Dimethylformamide (DMF) is a transparent liquid, miscible with water and most organic solvents. It is a common solvent for chemical reactions. Pure Dimethylformamide is odorless, but technical grade or spoiled Dimethylformamide has a fishy smell because it contains dimethylamine impurities. The name comes from the fact that it is the dimethyl substitution of formamide (amide of formic acid), and both methyl groups are located on the N (nitrogen) atom. Dimethylformamide is a high-boiling polar (hydrophilic) aprotic solvent that promotes the SN2 reaction mechanism. Dimethylformamide is manufactured using formic acid and dimethylamine. Dimethylformamide is unstable (especially at high temperature) in the presence of strong bases such as sodium hydroxide or strong acids such as hydrochloric acid or sulfuric acid, and hydrolyzes to formic acid and dimethylamine.

Uses:
Dimethylformamide is not only a chemical raw material with a wide range of uses, but also an excellent solvent with a wide range of uses. It can be used for wet spinning of synthetic fibers such as polyacrylonitrile fibers, and the synthesis of polyurethane; it can be used for plastic film making; it can also be used as a paint stripper for removing paint; it can also dissolve some low-solubility pigments, making the pigments with characteristics of dyes. In the petrochemical industry, it can be used as a gas absorbent to separate and produce sand worms; in medicine, it can be used to synthesize iodine, doxycycline, cortisone, vitamin B6, iodine, anthelmintic agent, pyrantel, N-methylacyl sarcomatin, antitumor acid, methoxyfen mustard, benzodiazepine, cyclohexyl nitrosourea, furofluorouracil, hemostatic acid, betamethasone, megestrol, cholestyramine Him, Pulmin, etc. It can also be used in product purification and gas analysis.
