Dimethylformamid

Dimethylformamide, commonly abbreviated DMF and known chemically as N,N-dimethylformamide, is a colorless, hygroscopic liquid that serves as a versatile polar aprotic solvent. Its chemical formula is C3H7NO, and it dissolves a wide range of organic and inorganic compounds, making it a staple in many chemical processes and industrial applications.

DMF is miscible with water and with most organic solvents. It has a relatively high boiling point of about 153°C and a melting point near −60°C, with a density around 1.0 g/mL at room temperature. These properties, along with its solvent power and chemical stability, contribute to its widespread use in laboratory and industrial settings.

Production and uses: DMF is produced on a large scale for use as a solvent in chemical synthesis, polymer processing, pharmaceuticals, and coatings. It is employed in the manufacture of polymers, dyes, pesticides, and other chemicals, and is also used as a reaction medium for various organic transformations due to its ability to stabilize reactive intermediates.

Safety and handling: DMF is a toxic chemical. Exposure can irritate the skin, eyes, and respiratory tract, and prolonged or high-level exposure may affect the liver and other organs. It is typically handled with appropriate engineering controls and personal protective equipment, including fume hoods, gloves, and eye protection. Containers should be kept tightly closed when not in use, and disposal is managed as hazardous waste in accordance with local regulations. Regulatory bodies commonly classify DMF as a hazardous substance and impose occupational exposure limits to minimize risk.
