| Application: | Nitric acid used as a reagent in: • The nitration of aromatic compounds, aromatic heterocycles, alkenes, active methylene carbons, etc. • Selective oxidation of organosulfur compounds to corresponding sulfoxides using a solid acid catalyst. • The oxidation of alcohols, aldehydes, esters, and heteroatoms. • The aromatization and dehydrogenation reactions. |
| General description: | Nitric acid is generally used as a primary reagent for the nitration of organic molecules. It is also used as a strong oxidizing agent in organic synthesis to perform the oxidative transformations. |
