Quality Control

Our 4-Pentenoic Acid Ethenyl Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopy (IR, NMR), to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles 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 2-8°C for extended stability. Keep container tightly sealed when not in use to minimize moisture absorption and prevent volatilization.
