Quality Control

Our Diphenylmethylidene(Cyclopentadienyl)(9-Fluorenyl)Zirconium Dichloride is manufactured under stringent inert atmosphere conditions to ensure batch-to-batch consistency and catalytic activity. Each lot undergoes rigorous analytical characterization, including NMR spectroscopy, elemental analysis (EA), and HPLC to verify identity, purity, and the absence of deleterious impurities. Certificates of Analysis (COA) detailing all specifications are provided with every shipment.

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 hygroscopic (moisture-sensitive) and easily oxidized (store under inert atmosphere). Allow the sealed container to reach ambient temperature before opening to minimize moisture condensation.
