Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized by advanced analytical techniques to guarantee identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications from HPLC, NMR, and GC-MS are available upon request to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition.
