Quality Control

Our Propanoic Acid, 2-Hydroxy-, Ethenyl Ester is produced under stringent quality management systems. Each batch undergoes rigorous analytical testing, including assay, purity verification, and impurity profiling, to ensure it meets precise customer specifications and industry standards. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials such as strong acids, bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. Due to its nature as a reactive monomer and organic ester, prolonged storage should be avoided, and containers should be kept under an inert atmosphere if specified.
