Description

Propanoic Acid, 2-Oxo-, Oxiranylmethyl Ester (9Ci) is a specialized organic compound featuring both an oxo (ketone) and an oxiranyl (epoxide) functional group. This unique bifunctional structure makes it a valuable high-purity chemical intermediate for advanced synthesis. It is primarily sought by pharmaceutical, agrochemical, and specialty polymer manufacturers for the development of novel active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of complex drug molecules, particularly those requiring epoxide or ketone functionality for further derivatization.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and plant growth regulators.
• Epoxy Resin Modifier: Serves as a reactive diluent or cross-linking agent to modify the properties of epoxy resin systems, enhancing flexibility or chemical resistance.
• Specialty Polymer Production: A monomer for creating polymers with specific thermal or mechanical properties for high-performance coatings and adhesives.
• Chemical Research & Development: A versatile reagent in organic synthesis labs for constructing complex molecular architectures.
• Cross-linking Agent: Utilized in formulations where its epoxide group can form covalent bonds with polymers, proteins, or other substrates.

Quality Control

Our Propanoic Acid, 2-Oxo-, Oxiranylmethyl Ester is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing to ensure high purity and consistency, meeting the exacting standards required for pharmaceutical and advanced chemical synthesis. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
