Application

3,4-Dichlorobenzoic acid was employed as internal standard during the multiresidue analysis of pharmaceuticals and personal care products by ultra performance liquid chromatography-positive/negative electrospray tandem mass spectrometry. It was used to study the metabolic fate of 4-chloro-3,5-dinitrobenzoic acid.

The main aim of the presented research is to introduce a new technique, ultra performance liquid chromatography-positive/negative electrospray tandem mass spectrometry (UPLC-ESI/MS/MS), for the development of new simultaneous multiresidue methods (over 50 compounds). These methods were used for the determination

When Acinetobacter sp. strain 4-CB1 was grown on 4-chlorobenzoate (4-CB), it cometabolized 3,4-dichlorobenzoate (3,4-DCB) to 3-chloro-4-hydroxybenzoate (3-C-4-OHB), which could be used as a growth substrate. No cometabolism of 3,4-DCB was observed when Acinetobacter sp. strain 4-CB1 was grown on benzoate.
