Quality Control

Every batch of our chiral ligands is produced under strict quality control to ensure high chemical purity and enantiomeric excess, which are critical for catalytic performance. We employ advanced analytical techniques including HPLC, NMR, and chiral analysis to verify identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment to support your quality and regulatory requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C) under an inert atmosphere (argon or nitrogen) to maximize shelf life and prevent degradation. The container should be kept in a well-ventilated area away from incompatible materials.
