High Purity 99.9% Dimethylformamide DMF Industrial Solvent CAS 68-12-2

Dimethylformamide (N,N-Dimethylformamide, DMF, CAS:68-12-2,EINECS:200-679-5, HS Code:2924199090, molecular formula C₃H₇NO, MW:73.09) is a colorless transparent liquid with faint amine-like odor, produced via advanced carbonylation of dimethylamine with carbon monoxide followed by multi-stage precision rectification purification. Our industrial grade DMF features ≥99.9% minimum purity with ultra-low moisture and residual impurities, offering exceptional solvency power for both organic and inorganic compounds, especially for high-molecular-weight polymers like polyurethane, polyacrylonitrile and PVC. As a universal polar aprotic solvent with high boiling point (153°C) and low volatility, it is widely used as reaction medium, extraction agent and processing solvent across polymer manufacturing, pharmaceutical synthesis, electronics and petrochemical industries. Our product strictly complies with international industrial standards, ensuring consistent quality and stable performance for various industrial applications.

Applications
Polyurethane (PU) Synthetic Leather Industry (Core Application, 42% Global Consumption)
Primary solvent for PU resin and synthetic leather slurry production, enabling uniform dissolution of polyurethane polymers and facilitating wet coagulation process to form porous leather structure. It ensures excellent elasticity, softness and durability of finished synthetic leather products.
Acrylic Fiber (Polyacrylonitrile) Manufacturing
Key solvent for wet spinning process of acrylic fibers, dissolving polyacrylonitrile polymer to form spinning dope. It allows precise control of fiber diameter and mechanical properties, producing high-quality acrylic fibers for textiles and clothing.
Pharmaceutical & Fine Chemical Synthesis
Versatile reaction medium and crystallization solvent for manufacturing antibiotics, antiviral drugs, anticancer agents and vitamins. Its high solvency power accelerates reaction rates and improves product purity and yield in complex organic synthesis processes.
Electronics Industry
High-purity DMF is used as cleaning agent for printed circuit boards (PCBs) and semiconductor wafers, effectively removing solder residues, flux and organic contaminants. It also serves as solvent for liquid crystal materials in LCD/OLED display production.
Petrochemical & Gas Processing
Selective extraction solvent for separating butadiene from C4 fractions, isoprene from C5 fractions and aromatics from aliphatic hydrocarbons. It also absorbs sulfur dioxide from industrial flue gases for desulfurization applications.
Other Industrial Uses
Solvent for PVC coatings, printing inks and adhesives; paint stripper for removing cured epoxy and polyurethane coatings; carrier for dyes and pigments in textile dyeing processes.
