Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of angiotensin II receptor antagonists like valsartan and related antihypertensive drugs. Its functional groups enable selective reactions for building complex heterocyclic structures. Also employed in the development of agrochemicals and dyes due to its aromatic aldehyde and amino group reactivity. Suitable for use in Schiff base formation and condensation reactions for creating bioactive molecules.
