General description
Titanium(IV) isopropoxide is a titanium-based coordination compound, commonly used in the asymmetric Sharpless epoxidation reaction of allylic alcohols. It is also used as a catalyst in Kulinkovich reaction for the synthesis of cyclopropanes.
Application
Commonly used as a precursor for the preparation of Titania (TiO2)
Novel metal oxide/phosphonate hybrids were formed from titanium(IV) isopropoxide in a two-step sol-gel process. Starting material for barium-strontium-titanate thin films. Used to make porous titanosilicates, potential ion-exchange materials for cleanup of radioactive wastes. Applied in the formation of a heterosupermolecule consisting of a TiO2 nanocrystallite-viologen electron acceptor complex whose light-induced electron transfer has been demonstrated.
Packaging
The 25 mL Sure/Seal™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.
