The odor threshold is 0.47100 ppm.Molecular weight= 73.11; Specific gravity (H2O:1)= 0.95;Boiling point = 153ºC; Freezing/Melting point = 261ºC;Vapor pressure= 3 mmHg at 20ºC; Flash point = 58ºC;Autoignition temperature= 444.5ºC. Explosive limits are:LEL = 2.2%; UEL= 15.2% at 100ºC. Hazard Identification(based on NFPA-704 M Rating System): Health 2,Flammability 2, Reactivity 0. Soluble in water.Potential Exposure: Tumorigen,Mutagen; Reproductive Effector; Human Data; Hormone,Primary Irritant. DMFA is used as a solvent for liquids,gases, and as a gasoline additive. Dimethylformamide haspowerful solvent properties for a wide range of organiccompounds. Because of its physical properties, this chemical has been used when solvents with a slow rate of evaporation are required. It finds particular usage in themanufacture of polyacrylic fibers, butadiene, purified acetylene, pharmaceuticals, dyes, petroleum products, and otherorganic chemicals.

Uses
N,N-Dimethylformamide (DMF) is a clear liquid that has been widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents. Dimethylformamide solutions are used toprocess polymer fibers, films, and surface coatings; to permit easy spinning of acrylic fibers; to produce wire enamels, and as a crystallization medium in the pharmaceutical industry.
DMF can also be used for formylation with alkyllithium or Grignard reagents. It is used as a reagent in Bouveault aldehyde synthesis and also in Vilsmeier-Haack reaction. It acts as a catalyst in the synthesis of acyl chlorides. It is used for separating and refining crude from olefin gas. DMF along with methylene chloride acts as a remover of varnish or lacquers. It is also used in the manufacture of adhesives, fibers and films.
