Used as an intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors and other bioactive molecules. Its structure allows for selective functionalization, making it valuable in medicinal chemistry for creating analogs with enhanced binding affinity. Commonly employed in research settings to construct complex heterocyclic systems, especially in the design of central nervous system agents and antitumor candidates. Also utilized in the preparation of labeled compounds for metabolic studies due to its stability and reactivity profile.
