Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide material with a typical purity of ≥95% (by HPLC), tailored to meet specific research requirements. Every batch is accompanied by comprehensive analytical data. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
