Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes, due to its aromatic amine group that facilitates diazotization and coupling reactions. It also serves in the preparation of pharmaceuticals, where the amino and methoxy functionalities contribute to building active compounds, especially in anti-inflammatory or analgesic agents. Additionally, it finds use in agrochemicals for developing herbicides and plant growth regulators. Its structure, featuring a carboxylic acid group, allows for easy modification, making it valuable in organic synthesis and research for developing new functional molecules.
