Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes due to its aromatic amine functionality. It serves in the production of pharmaceuticals, including certain antimicrobial and anti-inflammatory agents, where the aldehyde group allows for Schiff base formation. Also employed in the development of agrochemicals and photochromic materials. Its structure supports conjugation in organic semiconductors, making it useful in some electronic materials research. Additionally, it acts as a building block in the preparation of ligands for metal complexes in catalysis.
