La dimetilformamida (DMF) es un compuesto orgánico con una fórmula química de CHNO y un peso molecular de 73.09 g/mol. Es un líquido incoloro y transparente con un fuerte olor picante. DMF es un disolvente polar que puede disolver muchas sustancias orgánicas e inorgánicas, por lo que se usa ampliamente en campos químicos, farmacéuticos, textiles, electrónicos y de otro tipo. DMF se puede usar como solvente, agente reductor, catalizador, reacción intermedia, etc., y tiene una amplia gama de usos. Sin embargo, debe tenerse en cuenta que DMF es tóxico y cancerígeno para el cuerpo humano y debe usarse y almacenarse de manera segura .
