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) documenting key parameters are available upon request. We adhere to a cGMP-compliant quality management system for production relevant to pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a dry environment. For long-term stability, consider storing under an inert atmosphere such as argon or nitrogen to prevent oxidation.
