What is Pentafluorobenzoyl chloride?

Description

Pentafluorobenzoyl chloride is the acid chloride of pentafluorobenzoic acid. It is a sensitive derivatising reagent for the analysis of amines, amides and phenols by electron capture gas chromatography. It has a role as a chromatographic reagent. It is an acyl chloride and a perfluorinated compound. It derives from a pentafluorobenzoic acid.
2,3,4,5,6-Pentafluorobenzoyl chloride was used for derivatization of 5-androstenediol, testosterone, estradiol , dihydrotestosterone and estrone in a study to determine their serum levels. 2,3,4,5,6-Pentafluorobenzoyl chloride was used to derivatize dimethylamine(DMA) in study to develop a rapid and accurate GC–MS method for determination of DMA in human urine. 2,3,4,5,6-Pentafluorobenzoyl chloride was used in a study to detect the presence of Enterobacter cloacae in cultures of Leuconostoc mesenteroide by gas chromatography/mass spectrometry.
