N-Octyl-2-Pyrrolidone (NOP)
N-Octyl-2-pyrrolidone (NOP) is a high-purity specialty solvent and nonionic surfactant used in industrial formulations where strong solvency, wetting performance, and low volatility are required. BASF NOP combines high solvency power with low water solubility and surface-active properties, making it particularly valuable in agrochemical formulations, industrial cleaners, inks, and rubber systems. Product specification requires a minimum assay of 99.0% and a maximum water content of 0.5%
