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), with specifications tailored to meet the stringent requirements of pharmaceutical R&D and fine chemical synthesis. Certificates of Analysis (COA) detailing identity, purity (HPLC assay), chiral 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 a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, long-term storage under an inert atmosphere (e.g., nitrogen or argon) is recommended for optimal stability.
