Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide comprehensive analytical data to support your research and development needs. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request for every batch, ensuring full traceability and quality assurance.

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.
