Quality Control

Our Bis(Pentamethylcyclopentadienyl)Dimethylzirconium is manufactured under stringent conditions to ensure high purity and batch-to-batch consistency. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to verify identity and composition. Certificates of Analysis (COA) detailing all quality parameters are provided with every shipment to support your quality assurance protocols.

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. This material is both hygroscopic (moisture-sensitive) and easily oxidized; exposure to air or moisture must be strictly avoided to maintain product integrity. Handle and store only in a dry, inert environment.
