Quality Control

Every batch of our chiral ligands is produced and tested under strict quality management to ensure consistent high performance in sensitive catalytic applications. We provide comprehensive Certificates of Analysis (COA) detailing purity, chiral purity (enantiomeric excess), and identity confirmation via spectroscopic methods. Our quality systems support development under cGMP guidelines where required for pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C to maintain stability and prevent oxidation. Allow the container to reach room temperature in a dry environment before opening to minimize moisture condensation.
