Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our standard grade typically meets a purity specification of ≥97% (by HPLC), but higher purity grades are available upon request. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. Our quality protocols are designed to support cGMP compliance for pharmaceutical applications, and we can provide material for regulatory filings.

Storage

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