Quality Control

Our production of (n-Propylcyclopentadienyl)(Tetramethylcyclopentadienyl)Zirconium Dichloride adheres to stringent quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analytical characterization. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided and available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry place. This compound is moisture-sensitive (hygroscopic) and easily oxidized; therefore, containers must be kept sealed and handled in a controlled, dry environment to maintain stability and purity.
