Used primarily as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its structure supports the development of compounds with biological activity, particularly in creating antitumor and antimicrobial agents. Commonly employed in research settings to build complex heterocyclic systems. Also utilized in the preparation of dyes and fluorescent materials due to its conjugated aromatic framework. Its chlorine substituents allow for further functionalization through cross-coupling reactions, making it valuable in medicinal chemistry and materials science.
