Used as a key intermediate in the synthesis of complex pharmaceutical compounds, particularly in the development of targeted drug delivery systems. Its structure allows for selective conjugation with biomolecules, making it valuable in creating prodrugs and antibody-drug conjugates (ADCs). The chloro and carbamate functional groups enable controlled linkage to active pharmaceutical ingredients, enhancing stability and bioavailability. Also employed in polymer chemistry to introduce hydrophilic spacers with biodegradable characteristics, useful in designing responsive biomaterials.
