c-erium nitrate usage:
In organic synthesis, is useful as an oxidant for many functional groups as well as C-H bonds, especially those that are benzylic. alkenes undergo dinitroxylation, although the outcome is solvent-dependent. Quinones are produced from catechols and hydroquinones and even nitroalkanes are oxidized. Can provides an alternative to the Nef reaction; Catalytic amounts of aqueous can allow the efficient synthesis of quinoxaline derivatives. Can is traditionally used to release organic ligands from metal carbonyls. Can is used to convert para-methoxybenzyl and 3,4-dimethoxybenzyl ethers, which are protecting groups for alcohols. Can is also a component of chrome etchant, a material that is used in the production of photomasks and liquid crystal displays.
