Quality Control

Our Bis(1-Butyl-3-Methylcyclopentadienyl)Zirconium Dimethyl is manufactured under strict quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot is analyzed to confirm identity, purity, and absence of critical impurities. Certificates of Analysis (COA) detailing specific analytical results are provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to maintain stability. This material is moisture-sensitive (hygroscopic) and easily oxidized; handle and store exclusively under inert conditions using standard Schlenk line or glovebox techniques.
