Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals. Its reactivity allows for the introduction of thiophene moieties into larger molecules, which is valuable in drug development. Commonly employed in the preparation of antihypertensive agents and anti-inflammatory compounds. Also utilized in the production of dyes and functional materials due to the electron-rich nature of the thiophene ring. Suitable for use in Friedel-Crafts acylation and nucleophilic substitution reactions, making it a versatile building block in organic synthesis.
