Quality Control

Our [3,3',3''-(Phosphinidyne-κp)Tris[Benzenesulfonato]]-Palladate(3-) Sodium is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, ICP-MS for palladium content and trace metal impurities, and HPLC for purity assessment, to ensure consistent performance and high catalytic activity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent decomposition and maintain catalytic efficacy.
