Used as a key intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of biologically active compounds. Its aldehyde functional group allows for easy modification, enabling the formation of Schiff bases, alcohols, or carboxylic acids, which are valuable in drug design. Commonly employed in the preparation of thiophene-based heterocyclic compounds that exhibit antimicrobial, anti-inflammatory, or antitumor properties. Also utilized in the manufacture of dyes and functional materials due to its aromatic and electron-rich structure.
