Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the production of antihypertensive and anti-inflammatory drugs. It serves as a building block in agrochemicals for developing herbicides and fungicides due to its reactive functional groups. Also employed in the manufacture of dyes and specialty organic compounds where chlorothiophene derivatives enhance stability and biological activity. Its acetyl and chloro substituents allow for further chemical modifications, making it valuable in research and development of new bioactive molecules.
