Quality Control

Our 12-Cis,15-cis-Heneicosadienoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to confirm identity, purity, and isomeric composition. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical specifications. Our quality commitment ensures the material is suitable for demanding applications in research and development.

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 absorption.
