Used as a key reagent in the synthesis of various coordination complexes and metal-organic frameworks (MOFs), it plays a significant role in the development of materials with potential applications in catalysis, sensing, and photoluminescence. Its aldehyde functional group allows for easy modification, making it valuable in creating ligands for transition metal catalysts, which are essential in organic transformations. Additionally, it is employed in analytical chemistry as a chelating agent for the detection and quantification of metal ions, particularly iron, due to its strong binding affinity. In biochemistry, it serves as a building block for designing probes and inhibitors that target specific enzymes or biological processes. Its versatility also extends to the field of nanotechnology, where it is used to functionalize surfaces or nanoparticles for advanced material applications.
