Quality Control

Every batch of our chiral ruthenium catalysts is produced and tested under strict quality management protocols to ensure exceptional purity and consistent catalytic performance. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as chiral purity (enantiomeric excess), metal content, and spectroscopic identification. Our quality systems support compliance with cGMP standards for pharmaceutical applications, ensuring traceability and reliability for critical synthesis steps.

Storage

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