Application

Copper(II) nitrate hydrate plays a pivotal role as a catalyst in the oxidative coupling of 2,6-dimethylphenol, leading to the creation of an engineering polymer of significant importance. Beyond this, it has applications in the textile industry and is used in polishing agents for various metals. It also acts as a precursor to copper oxide, which is a catalyst employed in numerous organic transformations. In particular, Menke conditions utilize copper nitrate for aromatic nitrations, and when deposited on clay as a Claycop reagent, it is effective in organic reactions like the oxidation of dithioacetals to carbonyls and thiols to disulfides. Furthermore, copper(II) nitrate hydrate, combined with ammonium nitrate, is instrumental in producing p-type semiconductor CuO films, which possess a bandgap energy of 1.4 eV.
