Quality Control

Our Bis-(Fluorenyl)-Zirconium Dichloride is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive catalytic applications. Each lot undergoes comprehensive analysis, including purity assay and identity confirmation. Certificates of Analysis (COA) detailing all relevant specifications are available upon request to support your quality assurance and R&D documentation.

Storage

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