Quality Control

Our products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Quality is verified through analytical methods including HPLC, titration, and spectroscopic techniques to confirm identity, purity, and the absence of critical impurities. A Certificate of Analysis (COA) detailing all test results is available for every batch upon request, providing full traceability and assurance for your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 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.
