Used in pharmaceutical research as a key intermediate in the synthesis of kinase inhibitors, particularly in the development of targeted cancer therapies. It serves as a building block for compounds that modulate protein activity involved in cell signaling pathways. Its structure supports high binding affinity and selectivity toward specific enzymes, making it valuable in optimizing drug candidates for improved efficacy and reduced off-target effects. Also employed in medicinal chemistry for structure-activity relationship (SAR) studies to enhance pharmacokinetic properties.
