Gold(III) chloride solution can be used: As a starting material to prepare thiolate-stabilized gold nanoparticles. As an efficient catalyst for single-pot oxidative functionalization of alkanes and alcohols. As a catalyst for diastereoselective alkylation reactions with chiral benzylic acetates. Suitable precursormaterial for the synthesis of Gold nanorods by using Seed-Mediated Growth Methodwhich has been used for cancer cell imaging and photothermal therapy.
