General description

Gold(III) chloride hydrate is a yellowish crystalline solid and a powerful oxidizing agent widely used in gold electroplating, catalyst synthesis, and organic transformations.[1] [2]

Application

Gold(III) chloride hydrate can be used:
  • As a precursor to synthesize blue-emitting gold nanoclusters.[1]
  • As a dopant to enhance the optoelectronic properties of single-walled carbon nanotubes.[3]
  • To produce composite colloids of gold and polypyrrole.[2]
