Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of active pharmaceutical ingredients (APIs) where nitrogen-containing heterocycles are required. Its structure allows for functionalization in drug design, especially in creating analogs with biological activity. Also employed in agrochemical manufacturing for the production of certain pesticides and herbicides due to its reactivity and ability to form stable derivatives. Commonly utilized in research laboratories for building complex pyrazine-based molecules in medicinal chemistry.
