Quality Control

Our 2-Octen-4-One is produced under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including GC, IR, 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 adhere to cGMP principles where applicable to support our customers in regulated industries.

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 highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) after opening and minimize headspace. Keep away from heat, sparks, and open flame.
