Quality Control

Our (S,S)-Ethylenebis-(4,5,6,7-Tetrahydro-1-Indenyl)-Dimethyltitanium(IV) is manufactured under stringent inert atmosphere conditions to ensure batch-to-batch consistency and catalytic activity. Each lot undergoes rigorous analytical testing, including NMR spectroscopy and elemental analysis, to verify identity, purity, and chiral integrity. Certificates of Analysis (COA) detailing all specifications are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at temperatures between 2°C and 8°C (refrigerated) to maintain stability and prevent decomposition. This compound is moisture-sensitive (hygroscopic) and easily oxidized; therefore, it must be handled exclusively in a dry, oxygen-free environment using standard Schlenk line or glovebox techniques.
