N-Phenylanthranilic acid is widely used as an intermediate in the synthesis of various organic compounds, particularly in the production of dyes and pigments. Its structure makes it valuable for creating colorants with specific properties for textiles, inks, and coatings. Additionally, it serves as a reagent in analytical chemistry for the determination of metal ions, such as copper and iron, due to its chelating ability. In pharmaceutical research, it is utilized as a building block for developing compounds with potential therapeutic applications. Its role in organic synthesis also extends to the preparation of heterocyclic compounds, which are important in materials science and drug development.
