Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antituberculosis agents like isoniazid derivatives. It also serves as a ligand in coordination chemistry, forming stable complexes with metal ions for use in catalysis and material science. Its structure allows for hydrogen bonding and chelation, making it useful in designing sensors and functional materials. Additionally, it finds application in agrochemicals as a building block for herbicides and plant growth regulators.
