Quality Control

Our 5,8,11,14-Octadecatetraenoic Acid is produced and handled under strict quality management protocols. Each batch undergoes rigorous analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), identification (IR), and impurity profiles are available upon request to support your quality assurance and regulatory needs.

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 recommended cold temperatures (e.g., -20°C or below). The container should be kept in a cool, dry, and well-ventilated area, separate from strong oxidizing agents.
