Used as a key intermediate in the synthesis of fluorescent dyes and optical brighteners due to its strong chelating and luminescent properties. Employed in the development of sensors for metal ions, especially aluminum and zinc, in environmental and biological samples. Acts as a ligand in coordination chemistry for creating metal-organic frameworks with catalytic activity. Investigated for antimicrobial and antifungal applications in pharmaceutical formulations. Also utilized in corrosion inhibition studies for metals in industrial systems.
