Application
Gold(III) chloride trihydrate, also known as hydrogen tetrachloroaurate(III) trihydrate, is a versatile inorganic compound primarily recognized for its role as a gold catalyst. This golden yellow or yellow-red crystal serves multiple purposes in various fields. In analytical chemistry, it is an essential reagent for the identification and quantification of diverse substances. It also contributes to the synthesis of numerous gold compounds and is vital in the electroplating process, enabling the deposition of gold onto other metal surfaces. Furthermore, gold(III) chloride trihydrate is frequently used as a precursor in the production of gold nanoparticles, playing a significant part in biomedical applications due to its relatively low embryotoxicity compared to other nanoparticles. Additionally, it aids in the microanalysis of elements such as rubidium and cesium, and the determination of alkaloids. Beyond these applications, it is used in preparing gold standard solutions for graphite-furnace atomic absorption spectroscopy, controlling rods in nuclear reactors, and manufacturing electric light filaments, showcasing the compound's broad utility and significance.
