Overview

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.

Gold trichloride solution, commonly known as gold chloride or chloroauric acid, is widely used as a precursor in the synthesis of gold complexes and stable gold nanoparticles. It also has applications in catalysis.
