Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly for targeted cancer therapies. Its structure supports the development of compounds with high selectivity toward specific signaling pathways involved in tumor growth. The ethoxycarbonyl and methylthio groups enhance binding affinity and metabolic stability, making it valuable in optimizing drug candidates. Additionally, it serves in medicinal chemistry for exploring structure-activity relationships in spirocyclic diazane derivatives.
