Quality Control

Our Propanoic Acid, 2-Hydroxy-, 1-Methyl-2-Propenyl Ester is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting key specifications are available for every shipment upon request, supporting your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from strong bases and incompatible materials such as oxidizing agents. Due to the presence of an acrylate moiety and ester group, it is recommended to store under an inert atmosphere for long-term stability and to minimize potential polymerization.
