Quality Control

Every batch of our (R,R)-Ethylenebis-(4,5,6,7-Tetrahydro-1-Indenyl)-Zirconium(Iv)-(R)-(1,1'-Binaphthyl-2) undergoes rigorous analytical testing to ensure high purity and consistent catalytic performance. Our quality assurance protocol includes advanced spectroscopic and chromatographic methods to verify identity and quantify impurities. A comprehensive Certificate of Analysis (COA) detailing purity, chiral integrity, and specific analytical data is provided with each shipment to support your quality management systems.

Storage

Preserve in a tightly closed container, protected from light. Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), this material must be stored under an inert gas atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is between 2°C and 8°C. Allow the sealed container to equilibrate to room temperature before opening to minimize moisture ingress.
