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).
