}}3-Bromothiophene is an organosulfur compound with the formula C4H3BrS. It is a colorless liquid. It is a precursor to the antibiotic timentin and the vasodialator Cetiedil.[1]

Preparation

Unlike 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.
