Used as an intermediate in the synthesis of dyes and pigments, particularly in the production of azo dyes due to its aromatic amine groups that readily undergo diazotization. Also employed in the development of pharmaceuticals, where the amine functionalities allow for further chemical modifications to build active drug molecules. Its ester group facilitates solubility and reactivity in organic reactions, making it valuable in fine chemical synthesis. Additionally, it finds use in the preparation of specialty polymers and ligands for metal coordination in catalysis.
