Hydrogen tetrachloroaurate(III) (CAT: M086817) is a gold-based inorganic compound widely used as a precursor in gold nanoparticle synthesis, electroplating, and analytical chemistry. Appearing as an orange-yellow crystalline solid, it is highly soluble in water, producing acidic solutions containing Au³⁺ ions. In nanotechnology, HAuCl₄ serves as a key starting material for producing colloidal gold with applications in biosensing, drug delivery, and catalysis. It is also employed in microfabrication, microscopy staining, and refining of gold.
