1-Butylpyrrolidin-2-one（Cat No.:L019320）, also known as N-butyl-2-pyrrolidone (NBP), is a five-membered lactam featuring a butyl group attached to the nitrogen atom. This compound is a clear, high-boiling, polar aprotic solvent with excellent solubilizing properties for both organic and inorganic substances. It is widely used in pharmaceutical formulations, polymer processing, and surface treatments due to its low volatility and chemical stability. NBP serves as a safer alternative to N-methylpyrrolidone (NMP) in green chemistry contexts, offering lower toxicity while maintaining strong solvency for resins, dyes, and electrolytes in lithium-ion battery production.
