Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of biologically active pyrrole derivatives. Its aldehyde functionality allows for easy modification through condensation or reduction reactions, making it valuable in building complex heterocyclic systems. Commonly employed in the preparation of dyes, sensors, and functional materials due to its aromatic and electron-rich structure. Also utilized in research for designing novel compounds with potential antimicrobial or antitumor activity.
