Product Details

N-Methylformamide (NMF), a formamide derivative, is widely employed as an organic solvent. NMF molecule contains C=O and N-H groups, so it can act as a proton donor and acceptor. Due to its important physical properties such as high dielectric constant, high solubility, low conductivity and amphiprotic nature, it is suitable for use as a separation medium in capillary electrophoresis studies.
NMF is closely related to other formamides, notably formamide and dimethylformamide (DMF). However, industrial use and production of NMF are far less than for either of these other formamides. DMF is favored over NMF as a solvent due to its greater stability. Annual production of NMF can be assumed to be significantly less than the production of either formamide (100,000 tons) or DMF (500,000 tons).

Product Application Of N-Methylformamide CAS#123-39-7

N-Methylformamide is used to prepare methyl isocyanate. It is used as an extraction solvent for aromatic hydrocarbons and acts as a ligand in coordination chemistry. It is employed as a solvent in oil refineries and in aluminum electrolytic capacitors. Further, it is used as a reagent in organic synthesis. In addition to this, it is used as an investigational anticancer drug and an intermediate in the production of some pharmaceutical compounds.
