Application

Gold(I) chloride serves as a crucial starting material for synthesizing phosphine-ligated gold(I) complexes, which play a vital role as catalysts in synthetic chemistry. Additionally, it is employed in the production of metallic gold and in the preparation of compounds like potassium auric bromide and potassium chloride. With its characteristic yellow orthorhombic crystal form, a density of 7.6 g/cm³, and its unique solubility properties-it remains very slightly soluble in cold water and decomposes in hot water, while being soluble in hydrochloric and hydrobromic acids, as well as alkali cyanide solutions-Gold(I) chloride is a valuable reagent for various chemical processes.
