Methyl n-Propyl Ketone (MPK) ACS

Product Overview

Methyl n-Propyl Ketone (MPK) ACS Grade is a high-purity, colorless, flammable liquid solvent used in critical industrial and analytical processes. Also known as 2-Pentanone (CAS 107-87-9), this ACS-grade solvent offers reliable solvency with a moderate evaporation rate, ensuring precise control in formulation and synthesis. Manufactured to meet stringent purity specifications, MPK ACS typically demonstrates an assay of 99.8% (Range: 99.0–100.5%), aligning with ACS and USP-NF monograph expectations for reagents used in laboratory and manufacturing environments.

MPK is widely utilized in analytical chemistry, high-performance coatings, and chemical extraction processes due to its compatibility with both polar and nonpolar solutes. Its distinct physicochemical properties—including a boiling range of 102–104°C and low water content—enable consistent performance in HPLC mobile phases and surface coating applications. Proper storage and handling ensure the material maintains stability and compliance with rigorous industry safety standards.
