Quality Control

Our high-purity chiral catalyst is manufactured under controlled conditions to ensure batch-to-batch consistency and optimal catalytic performance. All materials undergo rigorous analytical testing, including HPLC for chiral purity and assay, elemental analysis, and spectroscopic identification. A comprehensive Certificate of Analysis (COA) detailing purity, enantiomeric excess (ee), and physical properties is provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Due to its moisture-sensitive and easily oxidized nature, this material should be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to equilibrate to room temperature before opening to prevent moisture condensation.
