Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like valsartan and related sartan-class drugs. It serves as a building block for constructing the core structure of these medications, which are widely prescribed for hypertension and cardiovascular diseases. Also employed in the development of agrochemicals and functional dyes due to its reactive amino and cyano groups, enabling diverse chemical transformations. Its structure supports conjugation in organic semiconductors and is explored in materials science for designing specialty polymers.
