Used as a key intermediate in the synthesis of pharmaceutical compounds, particularly in the development of kinase inhibitors for cancer treatment. It serves as a building block in medicinal chemistry due to its ability to enhance binding affinity and selectivity in drug candidates targeting neurological disorders and inflammatory diseases. Its structure supports the design of molecules with improved metabolic stability and blood-brain barrier penetration, making it valuable in CNS drug discovery. Also employed in the preparation of pyrazine-based bioactive molecules with antimicrobial and antiviral properties.
