Aqua regia is primarily used to produce chloroauric acid, the electrolyte in the Wohlwill process.
This process is used for refining highest quality (99.999%) gold. This is pure gold!!
Aqua regia is also used in etching and in specific analytic procedures. It is also used in some laboratories to clean glassware of organic compounds and metal particles.
This method is preferred over the "traditional" chromic acidbath for cleaning NMR tubes, because no traces of paramagnetic chromium can remain to later spoil acquired spectra.
Furthermore, chromic acid baths are discouraged because of the high toxicity of chromium and the potential for explosions. Aqua regia is itself very corrosive and has been implicated in several explosions due to mishandling.
