Quality Control

Our trans-9-Hydroxy-7-Nonenoic Acid is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing including HPLC, GC, and NMR to ensure identity, purity, and stereochemical integrity. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP standards for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants or an inert atmosphere.
