Used primarily in pharmaceutical research as a key intermediate in the synthesis of immunomodulatory drugs such as thalidomide analogs and lenalidomide derivatives. It serves as a structural analog in the development of compounds targeting inflammatory diseases, certain cancers (e.g., multiple myeloma), and autoimmune disorders (e.g., rheumatoid arthritis). Its core glutarimide structure supports modulation of cytokine production and T-cell activity, making it valuable in designing therapies for these conditions. Also investigated for use in neurodegenerative disease research due to its potential to cross the blood-brain barrier and influence neuroinflammatory pathways.
