Titanium isopropoxide

Titanium isopropoxide (CAS 546-68-9), abbreviated TTIP and also known as tetraisopropyl orthotitanate, is a reactive organotitanium compound used as a catalyst precursor.

Where is Titanium isopropoxide used?

• Specialty chemical manufacturing: sol-gel processing agent
• Coatings and thin films: controlled deposition of titanium dioxide layers on glass, metal and plastic substrates for photocatalytic, anti-reflective or barrier applications
• Polymers: crosslinker for polyesters and alkyd resins, improving adhesion and film integrity in industrial coatings and adhesives
• Personal care: surface-modification agent for pigment particles, particularly titanium dioxide in sunscreens and color cosmetics
• In pharmaceutical and biotech production it serves as a catalyst in stereoselective synthesis, notably asymmetric epoxidation.

Good to know: Moisture-sensitive; handling and storage under dry, inert conditions are standard.

Commercial specifications

• Purity: 97% or higher
• Packaging from small laboratory quantities to bulk drums under inert atmosphere
