Quality Control

Our 8-Octadecenoic Acid is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity confirmation, and impurity profiles.

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 nature as an unsaturated fatty acid, it is easily oxidized; for long-term storage, an inert atmosphere (e.g., nitrogen or argon) is recommended to maintain product integrity.
