(2-Chlorophenoxy)acetic acid

2-Chlorophenoxyacetic acid is a chemical used in the synthesis of a wide range of products. It can be obtained by reacting chlorophenols with acetic anhydride or acetyl chloride. 2-Chlorophenoxyacetic acid also has the potential to form impurities during its synthesis. The presence of these impurities can be detected using microscopy and dechlorinated, which can be identified by their increased solubility in carbon sources. In addition, 2-chlorophenoxyacetic acid has been shown to inhibit growth of P. aeruginosa and C. perfringens cultures when added at concentrations of 30 mM, but not methicillin-resistant Staphylococcus aureus (MRSA) cultures (2 µM). This may be due to the fact that MRSA strains have been shown to contain a bidentate ligand that binds with trifluoroacetic acid and prevents it from inhibiting bacterial growth.
