METHYLPYRROLIDONE Chemical compatibility with O-rings, rubbers, & plastics

Methylpyrrolidone is a colorless to pale yellow liquid with the chemical formula C₅H₉NO, used in various industrial and chemical applications. It is primarily employed as a solvent for polymers, resins, and coatings, and as a chemical intermediate in the production of pharmaceuticals, agrochemicals, and electronic chemicals. Methylpyrrolidone is also used in the formulation of cleaning agents and paint strippers. Despite its utility, methylpyrrolidone can cause skin, eye, and respiratory irritation if not handled properly. Proper handling, storage, and safety measures, including the use of personal protective equipment, are essential to ensure safe usage and prevent exposure. Adequate ventilation and spill containment measures are also necessary to prevent accidents and ensure safety.
