What is N-Methyl-2-pyrrolidone NMP CAS 872-50-4?

NMP(N-methyl-2-pyrrolidone) is a polar solvent with excellent properties. Because of its very high solubility, high boiling point and low freezing point, it is easy to use and has a wide range of applications. NMP can be completely miscible in most organic solvents (alcohols, ethers, ketones, aromatics, chlorinated hydrocarbons, etc.), and the solubility of organic matter and inorganic matter is large. It can be miscible with water in any proportion. Higher flash point than other similar solvents. Good chemical and thermal stability, non-corrosive.
