It is a colorless liquid. It is a precursor to the antibiotic timentin and the vasodialator Cetiedil.[1] PreparationUnlike 2-bromothiophene, the 3-bromo isomer cannot be prepared directly from thiophene. It can be prepared by debromination of 2,3,5-tribromothiophene:[2] The tribromothiophene is obtained by bromination of thiophene. {{clear|left}}See also
