Product Information
N,N-Dimethylformamide (DMF), with the chemical formula HCON(CH₃)₂, is an extremely important high-boiling polar aprotic solvent. It appears as a colorless transparent liquid with a faint amine-like or fishy odor. It possesses exceptionally strong solvating power and is miscible with both water and most organic solvents, earning it the reputation as a "universal solvent". DMF is a crucial solvent in polyurethane (PU) synthesis and acrylic fiber spinning, and is also widely used in pharmaceuticals, pesticides, electronic chemicals, and many other fields. It is important to note that DMF has certain hepatotoxicity and reproductive toxicity, requiring safe handling practices.
Product Nature

· A typical polar aprotic solvent, strongly solvates electrolytes and polymers.
· Undergoes hydrolysis in strong acids, strong bases, or at elevated temperatures, yielding dimethylamine and formic acid.
· Can be thermally decomposed at high temperatures (>350°C) to form dimethylamine and carbon monoxide.
· Can react with methyl iodide to form quaternary ammonium salts.
· Its carbonyl group can coordinate with metal ions to form complexes.
Product Usage
Polyurethane Industry: Serves as the primary solvent for manufacturing PU synthetic leather, elastomers, and coatings; its largest consumption area.
Synthetic Fibers: Used as a solvent in dry and wet spinning processes for producing polyacrylonitrile (acrylic) fibers.
Pharmaceutical Industry: Widely used as a reaction and crystallization solvent in the synthesis of pharmaceuticals like antibiotics and vitamins.
Organic Synthesis: Employed as an excellent polar aprotic solvent for numerous organic reactions (e.g., formylation, coupling reactions) and in purification processes.
Electronics Industry: Used as a cleaning agent in semiconductor and LCD manufacturing, and as a solvent component in lithium-ion battery electrolytes.
Pesticides & Dyes: Used as a solvent or reaction medium in the synthesis of pesticides and dyes.
Safety Matters
Health Hazards:
· Possesses significant hepatotoxicity and reproductive toxicity. Prolonged or high-level exposure can cause severe liver damage and affect fertility or fetal development.
· Strongly irritating and permeable to skin, eyes, and respiratory tract. Can be readily absorbed through the skin, increasing systemic toxicity risk.
· Inhalation of vapor may cause nausea, vomiting, abdominal pain, and liver dysfunction.
· Classified by IARC as Group 2B carcinogen (possibly carcinogenic to humans).Handling Protection:
· Must be handled in a fume hood or with effective local exhaust ventilation. Strictly prevent vapor accumulation and skin contact.
· Imperative to wear impermeable gloves (e.g., butyl rubber, Viton), chemical safety goggles, and protective clothing. Use effective organic vapor respiratory protection as needed.
· Provide safety showers and eye wash stations.
· Do not eat, drink, or smoke in work area. Wash thoroughly after handling.Storage & Transportation:
· Store in a cool, well-ventilated, dry place away from light. Keep containers tightly closed due to hygroscopicity.
· Store separately from strong oxidizers (e.g., peroxides, nitric acid), strong acids (e.g., hydrogen halides, sulfuric acid), strong bases (e.g., sodium hydroxide), and reducing agents.
· Use explosion-proof equipment and grounding.Fire Fighting:
· Combustible liquid, flash point 58°C (closed cup). Its vapor can form explosive mixtures with air.
· Use alcohol-resistant foam, dry powder, CO2, or water spray to extinguish fire.
· Use water spray to cool exposed containers and prevent explosion.
· Decomposes in fire, emitting toxic fumes including nitrogen oxides, carbon monoxide, and dimethylamine. Firefighters must wear self-contained breathing apparatus.
