Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the preparation of bioactive molecules that require substituted benzaldehyde derivatives. Its aldehyde and nitro functional groups allow for versatile chemical transformations, such as reduction of the nitro group to an amine or condensation reactions to form Schiff bases. Commonly employed in the development of dyes and fragrances due to its aromatic structure and reactivity. Also utilized in research settings for the construction of more complex organic molecules through multi-step synthesis.
