Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity, purity, and stereochemical integrity. Certificates of Analysis (COA) detailing batch-specific results are available upon request. We adhere to a cGMP-compliant quality management system suitable for pharmaceutical 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. For long-term storage, consider desiccants or inert atmosphere.
