Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antihypertensive and anticancer agents. Its structure allows for functionalization at multiple sites, making it valuable in medicinal chemistry for designing kinase inhibitors and other bioactive molecules. Also employed in the preparation of dyes and fluorescent compounds due to its aromatic and heterocyclic nature. Its derivatives show potential in agrochemicals, including herbicides and pesticides, owing to their biological activity.
