Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards and precise customer requirements. Every batch is analyzed to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) documenting the results of HPLC, NMR, and other relevant tests are available upon request. We adhere to a cGMP-compliant quality management system to ensure traceability and consistency for our global B2B clients.

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 under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Keep away from incompatible materials such as strong bases, amines, and oxidizing agents.
