Used as a key intermediate in the synthesis of pharmaceutical agents, particularly in the development of kinase inhibitors for cancer treatment. Its structure supports the creation of compounds with high selectivity toward specific enzyme targets, making it valuable in medicinal chemistry research. Also employed in the preparation of bioactive molecules for studying neurological disorders due to its ability to cross the blood-brain barrier. Commonly utilized in structure-activity relationship (SAR) studies to optimize drug candidates for improved potency and metabolic stability.
