Quality Control

Every batch of our metallocene precursors is manufactured and tested under strict inert atmosphere conditions to prevent decomposition. We employ advanced analytical techniques including NMR, HPLC, and elemental analysis to ensure high chemical purity and structural integrity. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with each shipment to support your catalyst development and quality assurance protocols.

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 and easily oxidized; containers must be kept sealed and only opened in a controlled, dry environment.
