Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive drugs and other biologically active compounds. It plays an important role in agrochemical manufacturing, serving as a building block for pesticides and herbicides due to its reactive functional groups. Its structure allows for easy modification in organic reactions, making it valuable in research and development of new heterocyclic compounds. Commonly employed in condensation and coupling reactions to form more complex molecules with enhanced biological activity.
