The article was titled 《Comprehensive GCxGC-qMS with a mass-to-charge ratio difference extraction method to identify new brominated byproducts during ozonation and their toxicity assessment》, and you may find the article in Journal of Hazardous Materials.Product Details of 31938-07-5 The information in the text is summarized as follows:
Ozonation might increase the risk of wastewater due to byproduct formation, especially in the presence of bromide. In this study, a new anal. method was developed to identify new brominated disinfection byproducts (Br-DBPs) during ozonation, using comprehensive two-dimensional gas chromatog.-single quadrupole mass spectrometry (GCxGC-qMS) connected with an electron capture detector in parallel. The obtained data were analyzed using a mass-to-charge ratio (m/z) difference extraction method. Over 1304 DBPs were detected in an ozonated phenylalanine solution Further screening of 635 DBPs was conducted using the m/z difference extraction method. Finally, the structures for 12 Br-DBPs were confirmed and for 4 Br-DBPs were tentatively proposed by comparison with the NIST library and standard compounds Eight of the confirmed Br-DBPs are first reported and identified: 2-bromostyrene, 1-bromo-1-phenylethylene, 2-bromobenzaldehyde, 3-bromobenzaldehyde, 4-bromobenzaldehyde, 2-bromophenylacetonitrile, 3-bromophenylacetonitrile and 4-bromophenylacetonitrile. These DBPs and 2,4,6-tribromophenol were detected at nanogram- to microgram-per-liter concentrations during ozonation of authentic water samples like algal bloom waters, wastewater treatment plant effluents, and surface water. The toxicities of these compounds were generally higher than that of bromate. The developed anal. method is a powerful technique for analyzing complex compounds and provides a novel way of identifying byproducts in future studies. In the experiment, the researchers used 2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5Product Details of 31938-07-5)
2-(3-Bromophenyl)acetonitrile(cas: 31938-07-5) has been used in the synthesis of 2-(1-cyano-1-(3-bromophenyl))methylidene-3-phenylthiazolidine-4,5-dione or a series of aminoethylbiphenyls, novel 5-HT7 receptor ligands.Product Details of 31938-07-5
