General description

4-Chloro-2-fluorobenzoic acid is a halogen benzoic acid. It is a non-liquid crystalline carboxylic acid derivative. It has been reported to form hydrogen bonded complexes with benzoylhydrazine-based azobenzene compound. Octanol/water partition coefficient Kow of 4-chloro-2-fluorobenzoic acid has been determined by shake-flask method.

Application

4-Chloro-2-fluorobenzoic acid may be used in the following studies:
  • As starting reagent for the synthesis of furosemide.
  • Synthesis of 4′-chloro-2′-fluoroacetophenone.
  • Synthesis of novel herbicidal isoxazolecarboxamides.
  • Preparation of potential liquid crystals.
