Quality Control

Our Ethyl 3-Methoxy-2-Butenoate is produced under a strict quality management system. Every batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) documenting all critical parameters are available upon request, supporting compliance with cGMP and ISO 9001 standards where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and oxidizing agents. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
