Description

2-Methyloxiran, also known as propylene oxide, is a versatile and highly reactive epoxide compound. It serves as a critical chemical intermediate in the synthesis of a wide range of industrial and consumer products, valued for its ability to undergo ring-opening polymerization and addition reactions. This high-purity chemical is essential for manufacturers in the polyurethane, pharmaceutical, and specialty chemical industries seeking reliable and consistent raw materials for their production processes.

Application

• Polyurethane Production: A primary raw material for manufacturing polyether polyols, which are key components in flexible and rigid foams, elastomers, and coatings.
• Propylene Glycol Synthesis: Used in the production of propylene glycol, a common ingredient in unsaturated polyester resins, antifreeze, and food/pharmaceutical applications.
• Surface-Active Agents: Acts as an intermediate in the manufacture of non-ionic surfactants and detergents.
• Pharmaceutical Intermediates: Serves as a building block in the synthesis of various active pharmaceutical ingredients (APIs) and other fine chemicals.
• Solvent and Stabilizer: Employed as an industrial solvent and as a stabilizer for certain chlorinated hydrocarbons.
• Chemical Derivatization: Utilized in organic synthesis for introducing hydroxypropyl groups into starch, cellulose, and other compounds.

Quality Control

Our 2-Methyloxiran is manufactured under stringent quality management systems to ensure batch-to-batch consistency and high purity. Quality is verified through comprehensive analytical testing including gas chromatography (GC) and other relevant methods. A detailed Certificate of Analysis (COA) is provided with each shipment, confirming compliance with agreed specifications. We adhere to relevant industry standards and can support requirements for cGMP, ISO, and REACH compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat, sparks, and open flames. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) to maintain purity and prevent peroxide formation. Keep away from incompatible materials such as strong acids, bases, and oxidizing agents.
