Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antitubercular drugs like isoniazid derivatives. Serves as a building block in the preparation of functionalized pyrazines for use in agrochemicals and dyes. Employed in materials science for developing conjugated organic compounds in electronic devices. Also utilized in coordination chemistry as a ligand precursor for metal-organic frameworks (MOFs) and catalysts. Its bifunctional aldehyde groups enable cross-linking in polymer chemistry and the formation of Schiff bases for further chemical modifications.
