Used as an intermediate in the synthesis of pharmaceuticals and bioactive compounds, particularly in the development of antimicrobial and anti-inflammatory agents. It serves as a building block in organic synthesis due to the presence of both aldehyde and phenolic functionalities, enabling Schiff base formation and further functionalization. Commonly employed in the preparation of chelating agents and fluorescent probes for metal ion detection. Also utilized in the fabrication of sensors and in coordination chemistry as a ligand for transition metal complexes.
