Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) documenting HPLC purity, NMR confirmation, and residual solvent levels are available upon request. We adhere to a quality management system suitable for supplying research and development as well as cGMP manufacturing.

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 incompatible materials.
