Quality Control

Our 1,1'-Isopropylidenezirconocene Dichloride is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high purity. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance and R&D documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (argon or nitrogen) to maintain stability and prevent decomposition.
