Used as a fluorescent probe in analytical chemistry due to its strong emission properties upon binding with metal ions, especially aluminum and zinc. Its hydroxyl and aldehyde functional groups allow for chelation, making it effective in detecting trace metals in environmental and biological samples. Also employed in the synthesis of Schiff bases and other heterocyclic compounds for pharmaceutical research. Shows potential in developing sensors for neurodegenerative disease markers because of its ability to cross cell membranes and respond to intracellular metal ion fluctuations.
