Used in pharmaceutical research as an intermediate for synthesizing bioactive molecules, particularly in the development of proteolysis-targeting chimeras (PROTACs). Its structure enables linkage between target protein ligands and E3 ubiquitin ligase recruiters, facilitating targeted protein degradation. Commonly employed in studies aiming to degrade disease-related proteins, especially in oncology and neurodegenerative disorders. Also utilized in medicinal chemistry for optimizing drug candidates requiring enhanced selectivity and degradation efficiency.
