Dimethylformamide (DMF) is a clear, colorless, hygroscopic liquid with a slight amine odor. The solvent properties of DMF are particularly attractive because of the high dielectric constant, the aprotic nature of the solvent, its wide liquid range and low volatility. It is frequently used for chemical reactions and other applications, which require a high solvency power. The product is known as a universal solvent. The high solubility of polyacrylonitrile in DMF, together with the good miscibility of DMF in water makes DMF the preferred solvent to produce acrylic fibers. Also, the spinning of polyurethane based elastomers is performed from DMF based solutions. Another significant application is the use of DMF as a solvent for polyurethane-based coatings on leather and artificial leather fabrics.
Application: It is used in the chemical industry as a solvent, an intermediate, and an additive; for example, in the production of pharmaceuticals, synthetic fibers, resins, agrochemicals, petrochemical industry etc.
1.Usage: N, N-dimethylformamide (DMF) is widely used as drug solvent. N, N-dimethylformamide is a dipole prophilic solvent with physical and chemical properties, so it is suitable for capillary electrophoresis (CE) solvent.
Dimethylformamide is an organic compound with the formula (CH)NCH. Commonly abbreviated as DMF, this colorless liquid is miscible with water and the majority of organic liquids. DMF is a common solvent for chemical reactions.
Dimethylformamide appears as a water-white liquid with a faint fishy odor having chemical formula HCON(CH3)2. It is widely used in industries as a solvent, an additive, or an intermediate because of its extensive miscibility with water and most common organic solvents.

Graphene has a two-dimensional structure of a carbonaceous new material. Graphene has excellent electrical, thermal and mechanical properties. Graphene oxide (GO) is a unique material with various oxygen containing functionalities such as epoxide, carbonyl, carboxyl and hydroxyl groups. Interest in GO increased dramatically after graphene, It was initially hoped that GO might be a synthetic precursor to graphene.
