Used as an intermediate in the synthesis of dyes and pigments due to its nitro and amino functional groups, which allow for further chemical modifications. Commonly employed in the production of azo dyes, where it undergoes diazotization and coupling reactions to form colored compounds. Also utilized in the preparation of certain pharmaceuticals and agrochemicals, serving as a building block for more complex molecules. Its ester group facilitates solubility and reactivity in organic synthesis, making it valuable in laboratory-scale reactions and industrial processes.
