Chloroauric acid is mainly used for alkaloid determination, electroplating gold, photography, gold powder, porcelain coloring, red glass manufacturing, special ink and treatment of tuberculosis. chloroauric acid can also be used as analytical reagent, such as microanalysis of rubidium (Rb) and cesium (Cs).chloroauric acid is used for semiconductor, electronic connector and local gold-plated of integrated circuit lead frame, also for printing circuit boards.

Chloroauric acid is the precursor used in the purification of gold by electrolysis.

Liquid-liquid extraction of chloroauric acid is used for the recovery, concentrating, purification, and analytical determinations of gold. Of great importance is the extraction of HAuCl4 from hydrochloric medium by oxygen-containing extractants, such as alcohols, ketones, ethers and esters. The concentration of gold(III) in the extracts may exceed 1 mol/L.The most frequently used extractants for this purpose are dibutyl glycol, methyl isobutyl ketone, tributyl phosphate, dichlorodiethyl ether (chlorex).、
