Import Dimethyl Formamide (Dmf) — Buy in wholesale FOB from Supplier in China

Dimethyl Formamide (DMF) is a clear, colourless liquid with a faint amine-like odor, miscible with water and most organic solvents. It is supplied in tech grade with a minimum purity of 99.9% by weight, as confirmed by gas chromatography. The product meets the HS code 2924191000 and complies with the specified physical limits: Pt-Co chrominance no more than 10, formic acid content under 25 ppm, moisture under 500 ppm, and iron content below 0.05 ppm. The aqueous solution at 20% concentration has a pH between 6.5 and 8.0 at 25°C, and electrical conductivity is held to 10 µS/cm or lower.

This grade of DMF is typically used as a solvent in the production of acrylic fibres and polyurethanes, where its high dielectric constant and boiling point enable consistent reaction control. It also serves as a reaction medium in pharmaceutical synthesis and pesticide manufacturing, and facilitates SN2 reactions and Grignard reagent chemistry. The presence of dimethyl acetamide is limited to 500 ppm, and methanol content is capped at 20 ppm to ensure low impurity interference. Standard industrial handling requires dry, cool storage away from incompatible oxidisers and strong bases.

Buyers in the textile, polymer, and fine chemical sectors source this material for batch processing and continuous production lines. The supplier offers FOB, CFR, CIF, FCA, and CPT trade terms with a monthly supply capacity of 1000 metric tons. Packaging is in 190 kg drums or ISO tanks, classified under Hazard Class 3, Packing Group III, and must be transported in compliance with UN 2265 regulations. Storage requires sealed containers in ventilated, climate-controlled facilities.
