General description

3-Bromo-5-iodobenzoic acid (BrIBA) is a halogen substituted carboxylic acid.

Application

3-Bromo-5-iodobenzoic acid may be used in the preparation of the following:
  • Phenyl(3-bromo-5-iodo)benzoate.
  • As starting reagent for the large-scale synthesis of the thromboxane receptor antagonist 3-{3-[2-(4-chlorobenzenesulfonamido)ethyl]-5-(4-fluorobenzyl)phenyl}propionic acid, via regioselective Heck cross-coupling reaction.
  • Methyl 3-bromo-5-iodobenzoate.
  • 3-Bromo-5-(triisopropylsilylethynyl)benzoic acid, via Sonogashira coupling reaction.
  • Trifluoroacetophenone.
