Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dye systems where its dual functional groups enable coupling reactions. Serves in the development of pharmaceuticals, especially in constructing heterocyclic compounds with biological activity. Applied in agrochemicals for creating herbicides and fungicides due to its aromatic and nitrogen-rich structure. Also utilized in coordination chemistry as a ligand for metal ions in catalytic systems. Shows potential in materials science for developing fluorescent probes and sensors owing to its phenolic and amino group interactions.
