Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of active pharmaceutical ingredients (APIs) with antihypertensive and anti-inflammatory properties. It serves as a building block in heterocyclic chemistry, enabling the construction of complex thiophene-based structures. Its acetyl and chloro functional groups allow for further chemical modifications, making it valuable in medicinal chemistry for drug development. Also utilized in agrochemicals for the design of certain pesticides and herbicides due to its reactive scaffold. Commonly employed in research laboratories for developing new organic compounds with potential biological activity.
