Application
Hydroquinone can be used as a reducing agent:
- To synthesize metal nanoparticles by reduction of metal salt precursors.
- For the reduction of aryldiazonium salt intermediates to aromatic compounds.
- In combination with ethylenediaminetetraacetic acid (EDTA) to prepare urchin-like gold nanoparticles via a one-pot seedless growth process.
