Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is analyzed using advanced techniques including HPLC, GC, and NMR to confirm identity, purity, and the absence of critical impurities. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place 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. Keep away from incompatible materials.
