Quality Control

Our 2,3-Dihydroxypropyl 12-Hydroxy-9-Octadecenoate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, identification, and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, physical constants, and other critical parameters is provided with every shipment to guarantee traceability and compliance.

Storage

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