Used in pharmaceutical research as a key intermediate in the synthesis of selective kinase inhibitors, particularly in the development of anticancer agents. Its structure supports binding to specific enzyme targets involved in cell signaling pathways. Due to the chiral center, the (S)-enantiomer shows higher biological activity and selectivity, making it valuable in optimizing drug efficacy and reducing side effects. Also explored in the design of central nervous system drugs owing to its ability to cross the blood-brain barrier.
