Quality Control

Our 5-Hexenoic Acid Methyl Ester is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP and ISO standards for production where required.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place at 2-8°C or as specified on the label. Due to its properties of being easily oxidized (store under inert atmosphere) and highly volatile, it is recommended to keep the container tightly sealed under an inert gas blanket (e.g., nitrogen or argon) and away from heat, sparks, and open flames. Keep away from incompatible materials such as strong oxidizing agents.
