Quality Control

Our 5,9,12-Octadecatrienoic Acid is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets precise customer specifications and consistent high-quality standards. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its polyunsaturated nature, this material is easily oxidized and should ideally be stored under an inert atmosphere (e.g., nitrogen or argon). Recommended long-term storage temperature is -20°C or below. Allow the sealed container to reach room temperature before opening to prevent moisture condensation.
