Quality Control

Our 9,10-Epoxy-12-octadecenoic acid is produced under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profile, and identity confirmation, to ensure it meets high-purity standards suitable for research and industrial applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from strong oxidizing agents.
