Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules with antimicrobial or antitumor properties. Its structure allows for selective functionalization in heterocyclic chemistry, making it valuable in medicinal chemistry research. Commonly employed in coupling reactions to build complex pyrrole derivatives found in active ingredients of crop protection agents and drug candidates. Also utilized in the preparation of fluorescent dyes and organic semiconductors due to its electron-rich aromatic core.
