Quality Control

Our 3-Hydroxy-7-Methyloctanoic Acid is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chiral purity assessment, to ensure it meets the high standards required for synthetic applications. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment and is available upon request.

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 opening to minimize exposure to atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
