Used primarily as an intermediate in organic synthesis, particularly in the pharmaceutical industry. It serves as a building block for active pharmaceutical ingredients (APIs) due to its nitrogen-containing heterocyclic structure, which can enhance bioavailability and binding affinity in drug molecules. Commonly employed in the development of central nervous system agents, antimicrobials, and kinase inhibitors. Its structural rigidity and functional groups allow for selective modifications, making it valuable in medicinal chemistry research and development.
