Used primarily as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of immunomodulatory and anticancer agents. Its structural features allow for selective modifications that enhance biological activity in target molecules. It plays a significant role in the preparation of derivatives related to thalidomide analogs, which are investigated for their efficacy in treating multiple myeloma and other hematological cancers. Additionally, it serves as a building block in medicinal chemistry for exploring new drug candidates with improved pharmacokinetic and safety profiles.
