Used as a highly selective chelating agent in advanced pharmaceutical synthesis, particularly in the purification and stabilization of complex peptide intermediates. Its rigid molecular framework enables precise stereochemical control during multi-step reactions, making it valuable in the production of chiral drugs. Also employed in specialized catalytic systems where metal ion coordination is required under mild conditions. Due to its bifunctional structure, it acts as a cross-linking agent in controlled drug delivery systems, enhancing the stability and bioavailability of active ingredients. Limited solubility in water but effective in polar organic solvents, it is typically used in anhydrous reaction environments for high-precision organic transformations.
