General description

4-Chlorobenzoic acid is a degradation product of indomethacin[1]. It is degraded by Acinetobacter sp. strain ST-1 and causes its dehalogenation to yield 4-hydroxybenzoic acid under both aerobic and anaerobic conditions[2].

Application

4-Chlorobenzoic acid can be used:
  • As a ligand to synthesize luminescent lanthanide complexes for bio-labeling or fiber communication applications.[3]
  • To prepare organotin(IV) chlorobenzoates exhibiting anticorrosion properties.[4]
  • As a ligand to synthesize di-n-butyl(4-chlorobenzoxy)(4-chlorobenzohydroxamato)tin(IV).[5]
