Used as an intermediate in the synthesis of targeted protein degradation therapeutics, particularly in the development of PROTACs (proteolysis-targeting chimeras). It serves to link E3 ligase ligands to target protein binders, enabling the degradation of disease-causing proteins. Its structure supports improved solubility and stability in cellular environments, making it valuable in medicinal chemistry for optimizing drug candidates. Commonly applied in oncology research due to its role in degrading proteins involved in cancer progression.
