Quality Control

Our 6-Octadecenal is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identity confirmation by IR spectroscopy and purity assessment by GC or HPLC, to ensure it meets precise customer specifications and industry standards. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and batch-to-batch consistency.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen) in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, minimize headspace in opened containers and handle under an inert gas blanket for long-term stability.
