Quality Control

Our production of this high-value catalyst adheres to strict quality protocols to ensure batch-to-batch consistency and optimal catalytic performance. Each lot is characterized using advanced analytical techniques, including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chiral purity is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C to maintain stability. Due to its hygroscopic and easily oxidized nature, the container should only be opened in a controlled, moisture-free, and oxygen-free environment.
