Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide material with a typical purity of ≥97% (by HPLC), tailored to meet specific project requirements. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are available upon request. Our quality management system supports development under cGMP guidelines for pharmaceutical applications.

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). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere for long-term storage to maintain stability and purity.
