Used as an intermediate in the synthesis of advanced fluorescent dyes and optical brighteners due to its strong luminescent properties when incorporated into conjugated systems. Its amino and ester functional groups allow for easy modification in organic synthesis, making it valuable in developing sensors for metal ions and pH detection. Also employed in the preparation of specialty polymers with enhanced thermal and photochemical stability. Shows promise in research related to metal-organic frameworks (MOFs) for sensing and catalytic applications owing to its rigid aromatic structure and chelating ability.
