N-Methylpyrrolidone (NMP): Versatile High-Solvency Polar Solvent
N-Methylpyrrolidone is a water-miscible polar aprotic solvent known for its exceptional solvating power across a broad range of organic and polymeric substrates. With a high boiling point of 202°C and low volatility, NMP is the solvent of choice for coating removals, polymer processing, and as a reaction medium in pharmaceutical and agrochemical synthesis. It has a favourable toxicological profile compared to many chlorinated alternatives.

Formulation Applications
In pharmaceutical manufacturing, NMP is used as a process solvent during API synthesis and for solubilising poorly water-soluble compounds in injectable and topical formulations. It is widely employed in electronics for photoresist stripping and in lithium-ion battery electrode coating. Polymer chemists use it to dissolve polysulfones, polyimides, and PVDF for membrane casting. Its high flash point and low vapour pressure make it safer to handle than many competing solvents in industrial settings.
