Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We offer material suitable for research and development use, with purity typically exceeding 95% (by HPLC). Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request. Specifications can be developed to meet specific customer requirements for advanced 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 using desiccant packs or storing under an inert atmosphere.
