Quality Control

Our production of Dimethylsilyl (T-Butylamido)Cyclopentadienyl Zirconium Dichloride adheres to stringent quality protocols to ensure batch-to-batch consistency and high catalytic performance. Each lot is characterized using advanced analytical techniques including NMR and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and assay is provided with every shipment to support your quality assurance and R&D processes.

Storage

Preserve in a tightly closed container, protected from light.
