It is used in the preparation of stable nanosized and underivatized colloidal gold particles in solution.
Hydrogen tetrachloroaurate(III) hydrate is used for microanalysis of rubidium, cesium and determination of alkaloids. Usually used as a harbinger for the preparation of gold (Au) nanoparticles. It is used in control rods in nuclear reactors and in the manufacture of light electric light filaments.
Gold (III) chloride hydrate,also known as chloroauric acid, is used as precursor to synthesize gold nanoparticles. It also exihibits very high catalytic activity.
