Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) detailing specific results for purity, isomer content, and key impurities are available upon request. We adhere to a cGMP-compliant quality management system to ensure reliability for research and development applications.

Storage

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