Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of anxiolytic and sedative agents. It serves as a core structure in modulating GABA receptors, contributing to central nervous system depressant effects. Also employed in the preparation of kinase inhibitors for cancer therapy. Its derivatives show potential in antimicrobial and anti-inflammatory applications. Widely utilized in medicinal chemistry for structure-activity relationship studies due to its bioisosteric properties with purine bases.
