Quality Control

Every batch of our chiral ligands undergoes rigorous analytical testing to ensure identity, purity, and enantiomeric excess meet the stringent requirements of catalytic applications. Our quality management system supports production under inert atmosphere to prevent oxidation. A comprehensive Certificate of Analysis (COA) detailing results from NMR, HPLC, and chiral analysis is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. For long-term stability, store under an inert atmosphere (argon or nitrogen) at 2-8°C. The material is easily oxidized (store under inert atmosphere) and light-sensitive (store away from light). Allow the sealed container to reach ambient temperature before opening to prevent moisture condensation.
