Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized using advanced analytical techniques including HPLC, NMR, and mass spectrometry to confirm identity and purity. Certificates of Analysis (COA) detailing batch-specific results are available upon request. We adhere to a quality management system suitable for supplying materials for research and development purposes.

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 (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
