Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of kinase inhibitors and other biologically active compounds. Its structure allows for easy functionalization, making it valuable in medicinal chemistry for building more complex molecules. Commonly employed in cross-coupling reactions and heterocyclic synthesis to create compounds with potential anti-inflammatory, anticancer, or antimicrobial activity. Also utilized in materials science for the preparation of organic semiconductors and fluorescent dyes due to its conjugated aromatic system.
