Quality Control

Our 9-Octyl-8-Heptadecene is produced under a stringent quality management system. Each batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and isomer distribution, to ensure consistency and compliance with agreed specifications. Certificates of Analysis (COA) documenting identity, purity, and key physical parameters are available for every shipment.

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 acids and oxidizing agents. Due to its nature as an easily oxidized compound, storage under an inert atmosphere (e.g., nitrogen) is recommended for long-term preservation of quality. Recommended storage temperature: 15-25°C.
