Quality Control

Our production of this high-purity metallocene adheres to stringent quality protocols. Every batch undergoes comprehensive analysis, including NMR spectroscopy for structural confirmation and HPLC for purity assessment, ensuring compliance with exacting R&D and process catalyst standards. A detailed Certificate of Analysis (COA) documenting chiral purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic and light-sensitive nature, this material should be stored under an inert atmosphere (argon or nitrogen) at a controlled room temperature (15-25°C). Keep the container in a cool, dry, and well-ventilated place, away from incompatible materials.
