It is used (particularly as its dimethylamine salt, known as quinclorac-dimethylammonium) as a (rather persistent) herbicide for the post-emergence control of weeds in rice, grass and turf. It is not approved for use within the European Union. It has a role as a herbicide, an agrochemical and a synthetic auxin. It is a quinolinemonocarboxylic acid, an organochlorine compound and a monocarboxylic acid. It is a conjugate acid of a quinclorac(1-)."}]
