Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of targeted cancer therapies. Its structure supports conjugation with biomolecules for drug delivery systems, enhancing selectivity toward tumor cells. Employed in research settings to design prodrugs that release active agents under specific physiological conditions. Also explored for its potential in creating novel alkylating agents due to the presence of chloroethyl groups, which can cross-link DNA strands, inhibiting cancer cell proliferation.
