Product Overview

Methyl n-Propyl Ketone (MPK), also known chemically as 2-Pentanone, is a colorless, flammable liquid ketone characterized by high solvency power and a medium evaporation rate. This Reagent Grade solvent (C5H10O) is manufactured to meet stringent purity standards, making it suitable for analytical applications, organic synthesis, and high-performance coating formulations.

MPK serves as an effective alternative to Methyl Ethyl Ketone (MEK) in applications requiring a slower evaporation rate to prevent solvent trapping or surface defects (blushing). Its low density and low viscosity facilitate efficient flow in lacquers and resin solutions. As a Reagent Grade chemical, this product undergoes rigorous testing to ensure minimal impurities, supporting consistent results in laboratory research and industrial processing.

Safety and Handling

Methyl n-Propyl Ketone is a flammable liquid and vapor. It must be stored in a cool, well-ventilated area designated for flammable liquids, away from ignition sources, heat, and direct sunlight. Keep containers tightly closed when not in use to prevent evaporation and minimize fire risk.

Personnel should wear appropriate Personal Protective Equipment (PPE), including solvent-resistant gloves and safety goggles. Use only in areas with adequate ventilation or exhaust systems to maintain airborne concentrations below regulatory limits. Refer to the Safety Data Sheet (SDS) for detailed emergency response, spill containment, and disposal guidelines.
