Quality Control

Our Heneicosanoic Acid, 21-Hydroxy- is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including identification by FT-IR, purity assessment by HPLC or GC, and specific tests for moisture and related substances. We provide full traceability and Certificates of Analysis (COA) are available for every shipment to ensure compliance with your research or production specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after each use to minimize exposure to atmospheric moisture. Keep away from strong oxidizing agents.
