Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of anticonvulsant and anti-inflammatory agents. Its structure supports the design of bioactive molecules that interact with central nervous system targets. Also employed in research settings for the preparation of quinazoline-based heterocyclic compounds with potential antimicrobial and anticancer properties. Commonly utilized in medicinal chemistry for structure-activity relationship (SAR) studies due to its ability to mimic purine scaffolds found in nucleic acids.
