N-Octyl-Pyrrolidone (NOP) is used as a solvent and dispersant in industrial applications. NOP is commonly found in coatings, cleaning products, and inks due to its ability to enhance the solubility and performance of various substances. It is also used in the production of polymers, where it improves the flexibility and adhesion of the final product. NOP's excellent solvent properties make it a key ingredient in many industrial formulations.
