Quality Control

Our Diphenylsilyl(Cyclopentadienyl)(9-Fluorenyl)Zirconium Dichloride is manufactured under stringent conditions to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to verify identity and purity. Certificates of Analysis (COA) detailing all specifications are available upon request.

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 compound is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air or moisture will degrade its catalytic activity.
