Widely used in the synthesis of pharmaceuticals, particularly as an intermediate in the production of antihypertensive drugs and other nitrogen-containing heterocyclic compounds. It serves as a building block in the development of kinase inhibitors and active ingredients in agrochemicals. Its functional groups enable easy modification for creating complex molecules in medicinal chemistry. Also employed in the preparation of dyes and fluorescent agents due to its aromatic and electron-rich structure. Commonly utilized in research laboratories for heterocycle formation and combinatorial chemistry.
