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 established specifications. A Certificate of Analysis (COA) detailing all test results is provided with every shipment and is available upon request.

Storage

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