Quality Control

Our iso-Propylidene(Cyclopentadienyl) (9-Fluorenyl)-Zirconium Dichloride is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to confirm identity and purity. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance and R&D documentation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry place at a controlled room temperature (15-25°C). Due to its moisture-sensitive nature, the container must be kept sealed and handled in a dry, inert environment to prevent decomposition.
