Used as an intermediate in the synthesis of pharmaceuticals, particularly in the development of serotonin receptor modulators and other central nervous system agents. Its structure supports the creation of bioactive molecules due to the electron-rich thiophene ring and the functional groups that allow for further chemical modifications. Commonly employed in research settings for designing new drug candidates with potential antidepressant or anxiolytic effects. Also utilized in agrochemical research for developing novel pesticides and herbicides owing to its stability and reactivity profile.
