Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of drugs targeting inflammatory diseases and certain cancers. Its structure supports the design of molecules with high selectivity for protein kinases such as JAK and TYK2. Also employed in medicinal chemistry for optimizing drug candidates due to its favorable metabolic stability and ability to enhance binding affinity. Additionally, it serves as a building block in the preparation of bioactive heterocyclic compounds explored for neurological disorders.
