Used as an intermediate in the synthesis of dyes and pigments, particularly for azo dyes, due to its ability to form stable aromatic structures with strong chromophoric properties. It also serves in the preparation of organic semiconductors and photoactive materials because of its extended π-conjugation system. Additionally, it finds use in research for developing novel polymers and as a building block in supramolecular chemistry owing to its hydrogen bonding capability through hydroxyl and carboxylic acid groups.
