Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. Its structure allows for selective binding to enzyme targets involved in cell signaling pathways, making it valuable in research for anticancer agents. Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to enhance potency and selectivity in drug candidates. Also utilized in the preparation of labeled derivatives for biochemical assays and receptor binding studies.
