Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anxiolytic and sedative agents. It serves as a structural scaffold in central nervous system (CNS) active compounds due to its ability to interact with benzodiazepine receptors. Also employed in the preparation of kinase inhibitors and other bioactive molecules in medicinal chemistry research. Its fused heterocyclic framework enhances metabolic stability and binding affinity, making it valuable in drug design.
