Used as a key intermediate in the synthesis of fluorescent dyes and sensors due to its ability to chelate metal ions and participate in condensation reactions. Its multiple hydroxyl and hydrazide functional groups make it suitable for developing chemosensors that detect metal ions like aluminum, zinc, and iron in environmental and biological systems. Also employed in the preparation of high-performance polymers and hydrogels, where it contributes to thermal stability and cross-linking. In medicinal chemistry, it serves as a building block for synthesizing bioactive hydrazone derivatives with potential antimicrobial and anticancer properties. Additionally, it finds use in corrosion inhibition formulations for metals in industrial systems.
