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.

Application

Nitric acid is used as a reagent in:
  • The nitration of aromatic compounds, aromatic heterocycles, alkenes, active methylene carbons, etc.
  • The oxidation of alcohols, aldehydes, esters, and heteroatoms.
  • The aromatization and dehydrogenation reactions.
