Quality Control

Every batch of our chiral ligands undergoes rigorous quality testing to ensure identity, purity, and enantiomeric excess meet the stringent requirements of catalytic applications. Our standard analytical package includes NMR, HPLC, and chiral analysis. Certificates of Analysis (COA) with full analytical data are provided to guarantee traceability and batch-to-batch consistency for your critical R&D and production processes.

Storage

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