Quality Control

Our cis-7,10,13,16,19-Docosa-Pentaenoic Acid is manufactured under strict quality management systems. Each batch is subjected to rigorous analytical testing, including HPLC and GC analysis, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all specified parameters. Our quality commitment supports applications requiring research-grade to GMP-compliant materials.

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. Keep away from heat and oxidizing agents.
