Used as an intermediate in pharmaceutical synthesis, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocycles. Commonly employed in cross-coupling reactions due to the presence of the bromo substituent, enabling the formation of C–C and C–N bonds. Also utilized in medicinal chemistry for the preparation of pyrazine-based drug candidates targeting cancer and inflammatory diseases.
