Used as a versatile reagent in coordination chemistry for synthesizing metal complexes, particularly in the development of luminescent materials and sensors. It is employed in the detection and quantification of metal ions, such as iron and copper, due to its strong chelating properties. Additionally, it serves as a building block in organic synthesis for creating heterocyclic compounds and ligands with specific electronic properties. In biochemistry, it is utilized in the study of enzyme inhibition and DNA interactions, aiding in the understanding of molecular recognition processes. Its aldehyde group allows for further functionalization, making it valuable in designing advanced materials and probes for analytical applications.
