Colorless to yellow liquid or low melting solid,
Chlorotriisopropoxytitanium(IV) solution may be used as a precursor for the synthesis of ultralow density ceramic materials. The product may be used to mediate a reductive amination reaction of 5α-cholestane-3,7-dione to yield aryl aminocholestanes.

Chlorotitanium triisopropoxide can be easily made from a 3:1 mixture of Titanium Tetraisopropoxide and Titanium(IV) Chloride,1 which can be distilled to give the pure reagent or used in situ.
When distilled under vacuum, the distillate sets slowly to a solid on standing. Stock reagents are made by dissolving the warm liquid in pentane, toluene, Et2O, THF, CH2Cl2,, and can be stored in a pure state or in solution under dry N2 for several months. The reagent is hygroscopic and is hydrolysed by H2O. [Reetz et al. Chem Ber 118 1421 1985.]
Chlorotitanium triisopropoxide is corrosive; moisture sensitive; flammable liquid; can be stored under nitrogen, in pure form or in solution, for months.
