Quality Control

Our (-)-Bis[1-[(1'S,2'S,5'R)-2'-I-Propyl-5'-Methylcyclohexyl]Indenyl]Zirconium (Iv) Dichloride is manufactured under stringent quality protocols to ensure batch-to-batch consistency and high catalytic activity. Each lot undergoes comprehensive analytical characterization, including NMR, HPLC, and elemental analysis, to verify identity, purity, and chiral integrity. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended long-term storage temperature is 2-8°C. Allow the sealed container to reach ambient temperature before opening to minimize moisture condensation.
