Used as a key intermediate in the synthesis of pharmaceuticals and bioactive molecules, particularly in the development of peptide conjugates and drug delivery systems. Its structure allows for easy functionalization, making it valuable in creating linkers for antibody-drug conjugates (ADCs) and other targeted therapies. Also employed in the preparation of chelating agents and in modifying biomolecules due to its amine and carboxylic acid groups, which facilitate coupling reactions. Commonly found in research settings for developing novel compounds in medicinal chemistry.
