Quality Control

Our high-purity organometallic catalysts are manufactured and handled under controlled inert atmospheres to prevent decomposition. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and elemental analysis, to confirm identity and purity. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to ensure traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry place. This material is moisture-sensitive and easily oxidized; prolonged exposure to air or ambient humidity should be avoided.
