Used in pharmaceutical synthesis, particularly in the development of targeted drug delivery systems due to its disulfide linkage, which is responsive to intracellular reducing environments. Commonly employed in the design of prodrugs and bioconjugates, especially antibody-drug conjugates (ADCs), where controlled release of active compounds is required. Its amine functional groups allow for easy coupling with carboxylic acids and activated esters, making it suitable for bioconjugation chemistry. Also utilized in polymer chemistry to introduce cleavable crosslinks in stimuli-responsive hydrogels and nanocarriers.
