N-Methyl-2-pyrrolidone

N-Methyl-2-pyrrolidone (NMP) is a highly polar organic compound with the molecular formula C5H9NO. It is a colorless to yellowish liquid with a slightly amine-like odor. NMP is soluble in water and most organic solvents, making it a versatile solvent in various industries.

NMP is primarily used as a solvent in the production of polymers, such as polyvinylidene fluoride (PVDF), polyvinyl pyrrolidone (PVP), and polyimides. It is also used in the electronics industry as a cleaning solvent for printed circuit boards and in the production of lithium-ion batteries. In addition, NMP is used as a solvent for pharmaceuticals, agrochemicals, and dyes.

NMP has been classified as a reproductive toxicant by the European Union and is on the list of chemicals of very high concern (SVHC) under the REACH regulation. It can be harmful if inhaled or absorbed through the skin and may cause irritation to the eyes and skin. Therefore, appropriate protective equipment, such as gloves, goggles, and a respirator, should be worn when handling NMP
