Used as a key intermediate in the synthesis of kinase inhibitors, particularly in pharmaceutical research targeting cancer therapies. Its structure allows for selective modification, making it valuable in developing compounds that modulate enzyme activity involved in cell signaling pathways. Commonly employed in the preparation of potent inhibitors for BTK (Bruton's tyrosine kinase) and other tyrosine kinases, aiding in the treatment of hematological malignancies. Also utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance binding affinity and selectivity in drug candidates.
