Used primarily as a ligand in coordination chemistry, it forms stable complexes with various metal ions, which are utilized in catalysis and material science. Its applications extend to the development of metal-organic frameworks (MOFs) due to its ability to create porous structures with high surface areas, useful for gas storage and separation. Additionally, it is employed in the synthesis of pharmaceuticals and agrochemicals, where its bifunctional nature aids in constructing complex molecular architectures. In analytical chemistry, it serves as a reagent for detecting and quantifying metal ions in environmental and biological samples. Its role in photochemical studies is also notable, as it participates in electron transfer processes, making it valuable in the design of light-harvesting systems and photovoltaic devices.
