Quality Control

Our Oxonol V is produced under a rigorous quality management system to ensure batch-to-batch consistency and high purity. Each lot is tested against stringent in-house specifications, which typically include identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture.
