Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards for research and development use. Every batch is characterized using advanced analytical techniques to confirm identity, purity, and consistency. Certificates of Analysis (COA) documenting detailed specifications are available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
