Widely used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of antitumor and antimicrobial agents. Its structure supports the formation of heterocyclic compounds with biological activity. Commonly employed in medicinal chemistry for constructing thiophene-based scaffolds, which are important in drug design due to their stability and interaction with biological targets. Also utilized in the preparation of dyes and functional materials where aromatic and sulfur-containing rings enhance electronic properties.
