Used in organic synthesis as a building block for pharmaceuticals and agrochemicals due to its reactive alkyne and heterocyclic structure. The compound serves as an intermediate in the development of bioactive molecules, particularly in the creation of novel flavor and fragrance compounds because of its pyrazine core, which is known for contributing roasted, nutty aroma notes. Its ethynyl group allows for further functionalization via click chemistry or coupling reactions, making it valuable in medicinal chemistry research and the design of specialty chemicals.
