Quality Control

Our Bis(1-Propyl-3-Methylcyclopentadienyl)Zirconium Dichloride is manufactured under stringent conditions to ensure batch-to-batch consistency and high catalytic performance. Each lot undergoes comprehensive analytical characterization, including NMR, elemental analysis, and purity assessment. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research or production 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 room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and light-sensitive; prolonged exposure to air, moisture, or light will degrade its catalytic activity.
