Description

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.

Packaging

4×25 mL in Sure/Seal™

100, 500 mL in glass bottle

1, 2, 2.5 L in glass bottle

The 25 mL Sure/Seal^™ bottle is recommended as a single-use bottle. Repeated punctures will likely result in decreased performance of product.

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.
