Quality Control

Our All-cis-4,7,10,13,16-Docosapentaenoic Acid is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography (HPLC, GC) and spectroscopic methods, to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing purity, specific tests, and results are provided to guarantee it meets the stringent requirements for research and development applications.

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 sealed container to reach room temperature before opening to minimize moisture condensation. Keep away from heat and incompatible materials.
