General description

4-Chlorobenzoic acid is a degradation product of indomethacin. It is degraded by Acinetobacter sp. strain ST-1 and causes its dehalogenation to yield 4-hydroxybenzoic acid under both aerobic and anaerobic conditions.

Application

4-Chlorobenzoic acid can be used:
  • As a ligand to synthesize luminescent lanthanide complexes for bio-labeling or fiber communication applications.
  • To prepare organotin(IV) chlorobenzoates exhibiting anticorrosion properties.
  • As a ligand to synthesize di-n-butyl(4-chlorobenzoxy)(4-chlorobenzohydroxamato)tin(IV).

Acinetobacter sp. strain ST-1, isolated from garden soil, can mineralize 4-chlorobenzoic acid (4-CBA). The bacterium degrades 4-CBA, starting with dehalogenation to yield 4-hydroxybenzoic acid (4-HBA) under both aerobic and anaerobic conditions, suggesting that the dehalogenating enzyme in the strain is
