Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Every batch is characterized to confirm identity, purity, and enantiomeric excess. Certificates of Analysis (COA) are available upon request, detailing key parameters such as assay (HPLC), chiral purity, and impurity profiles. 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 room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
