Quality Control

Our cis-6,9,12,15-Octadecatetraenoic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the stringent requirements for research and industrial use. A Certificate of Analysis (COA) detailing specific results for purity, identity, and related substances is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store at -20°C or below under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake and thermal stress.
