Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. We provide comprehensive analytical data, including HPLC purity, identity confirmation (IR, NMR), and impurity profiling. Certificates of Analysis (COA) are available upon request, detailing batch-specific results for all critical parameters.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from incompatible materials such as strong oxidizing agents, strong bases, and strong acids. Due to the phenolic hydroxyl groups, this compound may be sensitive to oxidation; prolonged storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal long-term stability.
