At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing clear and comprehensive information about the chemicals we supply. This article focuses on 2-Methyl-1,3-Propanediol (MPO), CAS 2163-42-0, detailing its essential chemical properties and its broad spectrum of industrial applications.

MPO has the molecular formula C4H10O2 and a molecular weight of approximately 90.121 g/mol. It is characterized as a colorless, low-viscosity liquid with a high boiling point, reported around 212°C. Crucially, MPO has a low freezing point, ensuring it remains liquid even at sub-zero temperatures, which simplifies handling and storage. Unlike some other diols, MPO exhibits significantly lower hygroscopicity, meaning it absorbs less moisture from the atmosphere, contributing to greater formulation stability and product integrity.

The chemical structure of MPO is key to its functionality. It is a diol with two primary hydroxyl groups positioned on a branched carbon chain. This configuration provides excellent solvency for both polar and non-polar substances, making it a versatile component in various formulations. Its purity standard is typically 99.5% minimum, ensuring consistent performance in demanding applications.

The primary industrial applications for MPO are extensive, reflecting its versatility. It is widely used in the production of unsaturated and saturated polyester resins, where it imparts improved flexibility, toughness, and weatherability. In the polyurethane industry, it acts as a chain extender and intermediate for polyester polyols. MPO also finds use in plasticizers, cosmetics, personal care products, and as a solvent. Understanding these chemical properties and uses is vital for any manufacturer looking to source this valuable chemical intermediate. NINGBO INNO PHARMCHEM CO.,LTD. offers MPO with high purity and reliable supply.
