Used in pharmaceutical research as a key intermediate in the synthesis of bioactive molecules, particularly in the development of kinase inhibitors and central nervous system agents. Exhibits potential in the design of compounds targeting neurological disorders due to its ability to cross the blood-brain barrier. Also employed in the creation of fluorescent probes for biochemical assays, leveraging its heterocyclic structure for enhanced binding selectivity. Commonly found in early-stage drug discovery for optimizing lead compounds with improved metabolic stability and receptor affinity.
