Used as an intermediate in the synthesis of pharmaceuticals and agrochemicals, particularly in the development of bioactive molecules due to the presence of the chlorothiophene ring. Its ester functionality allows for further chemical modifications, making it valuable in constructing more complex organic compounds. Commonly employed in the production of selective herbicides and fungicides. Also utilized in research for developing new therapeutic agents, especially in medicinal chemistry where thiophene derivatives show potential in treating inflammatory and neurological disorders.
