Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch is characterized to confirm identity, chiral purity, and chemical purity. Certificates of Analysis (COA) detailing specific results for chiral HPLC assay, enantiomeric excess (ee), and impurity profiles are available upon request. We adhere to strict internal quality protocols suitable for research and development applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere such as nitrogen or argon after opening to prevent degradation.
