Used as a key intermediate in the synthesis of pharmaceuticals, particularly in the development of drugs targeting central nervous system disorders. Its structure allows for easy functionalization, making it valuable in creating biologically active molecules. Commonly employed in the preparation of serotonin and dopamine receptor modulators. Also utilized in agrochemicals for the production of novel pesticides and herbicides due to its stability and reactivity. Frequently applied in research settings for the construction of thiophene-based compounds in medicinal chemistry.
