Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, detailing key parameters such as chiral purity, chemical identity, and assay. We adhere to strict analytical protocols, including NMR, HPLC, and elemental analysis, to guarantee batch-to-batch consistency and performance reliability for your catalytic applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C or as specified on the label. This compound is hygroscopic (moisture-sensitive) and easily oxidized; therefore, it must be handled in a controlled, dry environment to maintain stability and catalytic activity.
