Used as a key intermediate in the synthesis of immunomodulatory drugs, particularly in the development of cereblon E3 ligase modulators. It plays a critical role in targeted protein degradation therapies, including treatments for certain cancers such as multiple myeloma and myelodysplastic syndromes. Its structure enables selective binding to cereblon, facilitating the degradation of disease-causing proteins. Also employed in research for developing novel therapeutics in oncology and inflammatory diseases.
