Used in the synthesis of dyes and pigments due to its ability to form complex aromatic structures with strong color properties. Serves as an intermediate in the production of pharmaceuticals, particularly in developing compounds with antioxidant and anti-inflammatory activity. Employed in research for the development of organic semiconductors and photoactive materials because of its conjugated ring system that supports electron delocalization. Also utilized in the preparation of fluorescent probes and sensors, where its hydroxyl groups enable functionalization for selective detection of metal ions or biomolecules.
