Quality Control

Our Octadeca-9,12,15-Trienoic Acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling to ensure it meets the required specifications for your application. A Certificate of Analysis (COA) detailing purity, physical characteristics, and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C. The material is easily oxidized and should be kept away from heat and oxidizing agents. Allow the container to reach room temperature before opening to prevent moisture condensation.
