Used primarily as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) for antiviral and antibacterial agents. Its structure allows for selective functionalization, making it valuable in constructing nitrogen-containing heterocyclic compounds. It is also employed in agrochemical synthesis, contributing to the creation of certain pesticides and herbicides due to its reactivity and stability in multi-step reactions. Additionally, it serves in research laboratories for the preparation of pyrazine-based derivatives with potential biological activity.
