CAS 16903-35-8 — Ácido tetracloroaurato(III)

Tetrachloroaurate (III) acid (HAuCl4) is a gold(III) chloride complex dissolved in hydrochloric acid, widely used in electronics for gold plating, catalysis, and as a precursor in nanotechnology and chemical synthesis. It appears as a yellow to red-brown solution, highly soluble in water and polar solvents. This hazardous chemical requires careful handling due to its corrosive and toxic properties.
