Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive drugs and other nitrogen-containing heterocyclic compounds based on pyrazine scaffolds. Its structure supports the construction of complex molecules in medicinal chemistry. Also employed in agrochemical research for designing novel pesticides and herbicides due to its bioactive pyrazine core. Commonly utilized in organic synthesis for creating pyrazine-based derivatives with potential applications in materials science and drug discovery.
