Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive analytical testing, including HPLC, GC, and NMR, to verify identity and purity against stringent internal specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment. Our commitment to quality supports compliance with cGMP and other relevant pharmaceutical and industrial standards.

Storage

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