Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) are provided, detailing results from analytical methods including HPLC, NMR, and optical rotation measurement. We adhere to cGMP principles for manufacturing and quality management where applicable, ensuring traceability and consistency for research and development use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); therefore, containers must be kept tightly sealed and consideration should be given to storage under an inert atmosphere for long-term preservation of quality. Keep away from incompatible materials.
