Quality Control

Every batch of (R,R)-Ethylene Bis(4,5,6,7-Tetrahydro-1-Indenyl)Difluorotitanium(Iv) is synthesized and handled under stringent inert atmosphere conditions to prevent decomposition. Our quality assurance protocol includes comprehensive analytical characterization to ensure high catalytic purity and stereochemical integrity. Certificates of Analysis (COA) detailing NMR (¹H, ¹³C, ¹⁹F), elemental analysis, and purity assay are provided to guarantee batch-to-batch consistency for your critical R&D and process development work.

Storage

Preserve in a tightly closed container, protected from light. This material is both easily oxidized and hygroscopic (moisture-sensitive) and must be stored under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C. For long-term stability, storage at -20°C under inert gas is recommended. The container should be kept in a cool, dry, and well-ventilated area, away from incompatible materials such as strong acids and strong oxidizing agents.
