Quality Control

Our (All-Z)-6,9,12,15,18-Heneicosapentaenoic Acid Ethyl Ester is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed chromatographic data are provided for every shipment, supporting compliance with research and cGMP-grade requirements where applicable.

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., argon or nitrogen) to prevent oxidation. Allow the container to reach room temperature in a desiccator before opening to minimize moisture uptake.
