General description

2,4-Dichlorobenzoic acid is the degradation product of chlorfenvinphos in water treated by photo-fenton driven by solar irradiation.

Application

2,4-Dichlorobenzoic acid was used in solid-phase extraction and gas chromatographic determination of polar acidic herbicides in surface water. It was used as reagent during the synthesis of pyrimido[2′,1′:2,3]thiazolo[4,5-b]quinoxaline derivatives. It was used as starting reagent during the synthesis of 1-(substituted)-1,4-dihydro-6-nitro-4-oxo-7-(sub-secondary amino)-quinoline-3-carboxylic acids.
