Packaging and shipping
N-Methylformamide (NMF) is a colorless and transparent viscous liquid with an ammonia-like odor. Its chemical formula is C₂H₅NO and its molecular weight is 59.07. As a methylated derivative of amide, NMF, due to its extremely high dielectric constant, high boiling point, excellent solubility and relatively low toxicity, has become a key functional solvent and intermediate connecting traditional chemical industry and high-end manufacturing. It plays an indispensable role in fields such as pesticides, medicine, new energy batteries, electronic chemicals and special high-molecular materials.

Product Introduction
N-Methylformamide (NMF) is a colorless and transparent viscous liquid with an ammonia-like odor. Its chemical formula is C₂H₅NO and its molecular weight is 59.07. As a methylated derivative of amide, NMF, with its extremely high dielectric constant, high boiling point, excellent solubility and relatively low toxicity, has become a key functional solvent and intermediate connecting traditional chemical industry and high-end manufacturing. It plays an indispensable role in fields such as pesticides, medicine, new energy batteries, electronic chemicals and special high-molecular materials.
The core value of NMF lies in its high boiling point, strong polarity and good thermal stability, which gives it unique advantages in processes requiring high temperature, high polarity and inert reaction environments.
Pesticide synthesis (traditional core application):
Key intermediates: They are important intermediates for synthesizing highly effective and low-toxicity insecticides and acaricides such as monomethylphosoline and dimethylphosoline.
Pharmaceutical intermediate synthesis (high growth, high value-added field):
Efficient solvents and reaction media: Due to its excellent polar non-polar characteristics, it is widely used in peptide synthesis, heterocyclic construction, chiral resolution and the synthesis of key raw materials for drugs such as nucleosides, cephalosporins, and anti-tumor drugs (such as osimetin), as well as reaction media in the formulation of electrolytes. Its relatively lower toxicity (compared to DMF) gives it an advantage in high-end drug synthesis.
New energy battery materials (emerging high-growth field):
Key components of lithium battery electrolytes: Due to its extremely high dielectric constant (~180) and wide electrochemical window, it is used as a key solvent or co-solvent in the synthesis of new lithium salts (such as LiFSI, LiTFSI), the preparation of solid electrolyte precursors, and the formulation of electrolytes, effectively improving ionic conductivity, improving low-temperature performance and cycle stability. In new energy storage systems such as zinc-ion batteries, NMF is also studied for use in constructing high-safety, dendrite-free electrolyte systems.
Electronic chemicals and precision manufacturing (highest technical barriers field):
Semiconductor and display materials: Electronic-grade high-purity NMF is used in the preparation of stripping solutions for photomasks in semiconductor manufacturing, wafer cleaning (metal ion chelation), and the preparation of OLED liquid crystal orientation agents, with extremely high requirements for purity (metal ions ≤ 1 ppm), moisture (≤ 50 ppm), and batch stability.
Special polymers and fibers:
High-performance solvents: Excellent solubility for special high-molecular materials such as polyacrylonitrile, polyimide, and aramid, applicable to wet spinning, film formation and other processes.
Other fields: Used as a selective extraction solvent in petrochemicals, a solvent for synthetic leather and artificial leather, and a reaction medium for the synthesis of dyes and fragrances.
