Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is analyzed to confirm identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing specific results for chiral purity (enantiomeric excess), chemical purity (by HPLC/GC), and other critical parameters are available upon request. We adhere to cGMP principles for production where applicable to support advanced research and development projects.

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 nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect stability and handling properties. Keep away from incompatible materials.
