Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its nitro and carboxylic acid functional groups allow for further chemical transformations, such as reduction of the nitro group to an amine, enabling the production of substituted anilines. Commonly employed in the development of active ingredients in herbicides and dyes due to its aromatic structure and reactivity. Also utilized in research settings for constructing more complex organic molecules through coupling reactions or cyclizations.
