Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure enables selective binding to enzyme active sites, making it valuable in designing targeted therapies. Also employed in the preparation of biologically active compounds for neurological and inflammatory disorders due to its ability to cross cell membranes and interact with central nervous system receptors. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies to optimize drug potency and selectivity.
