Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antiviral and antibacterial agents. Its structure allows for selective functionalization, making it valuable in creating active pharmaceutical ingredients (APIs) with enhanced biological activity. Also employed in agrochemicals for the production of herbicides and pesticides due to its ability to improve compound stability and target specificity. Commonly utilized in research laboratories for heterocyclic compound development and in the design of novel organic molecules requiring pyrazine-based scaffolds.
