Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity and purity, with key parameters controlled to meet the demanding requirements of research and high-tech applications. Certificates of Analysis (COA) detailing specific test results are available upon request.

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 an inert atmosphere.
