Widely used in pharmaceutical research, this compound serves as a key intermediate in the synthesis of immunomodulatory drugs. It is particularly important in the development of cereblon E3 ligase modulators, which are a class of therapeutics used in treating multiple myeloma and other hematological cancers. Its structure enables selective protein degradation through the ubiquitin-proteasome system, making it valuable in targeted cancer therapy. Additionally, it is used in the design of small-molecule drugs that can recruit specific disease-causing proteins for degradation. Due to its role in enhancing drug specificity and efficacy, it is a critical scaffold in modern drug discovery, especially in oncology and inflammatory disease research.
