Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of central nervous system agents. It serves as a building block for quinazoline-based derivatives that exhibit potential anxiolytic, sedative, or anticonvulsant activities. Its structure allows for functional modifications that enhance binding to GABA receptors, making it valuable in medicinal chemistry for designing new neuroactive drugs. Also investigated for use in agrochemicals due to its heterocyclic stability and reactivity profile.
