In 2022,Liu, Jie; Xu, Xinxin; Wu, Aihong; Song, Shanshan; Xu, Liguang; Xu, Chuanlai; Kuang, Hua; Liu, Liqiang published an article in LWT–Food Science and Technology. The title of the article was 《Immunochromatographic assay for the rapid and sensitive detection of etoxazole in orange and grape samples》.Name: Ethyl 4-bromobutyrate The author mentioned the following in the article:
Etoxazole, a novel organofluorine pesticide, has been widely used against various mites in fruits and vegetables. In this study, we designed an etoxazole-hapten and produced a highly sensitive monoclonal antibody (mAb) against etoxazole with a half-maximal inhibitory concentration of 4.04 ng/mL. Based on the mAb, we developed an immunochromatog. assay (ICA) for the detection of etoxazole in orange and grape samples. In the qual. detection, the visible limit of detection (vLOD) and cut-off value were 10 and 100 ng/g (fresh weight), resp. In the quant. detection, the LOD value was 2.03 ng/g (fresh weight) in orange and 2.52 ng/g (fresh weight) in grape samples. The recovery rates ranged from 94.7 ± 4.0% to 103.3 ± 3.8%, with CVs of 3.7-4.2% and 96.4 ± 3.4% to 106.1 ± 5.5%, with CVs of 3.5-5.2% for etoxazole in grape and orange samples, resp. The ICA results were similar to those of LC-MS/MS. Therefore, our developed ICA is a rapid, sensitive, and simple tool for screening etoxazole residues in fruits and vegetables. In addition to this study using Ethyl 4-bromobutyrate, there are many other studies that have used Ethyl 4-bromobutyrate(cas: 2969-81-5Name: Ethyl 4-bromobutyrate) was used in this study.
Ethyl 4-bromobutyrate(cas: 2969-81-5) belongs to bromides. A variety of minor organobromine compounds are found in nature, but none are biosynthesized or required by mammals. Organobromine compounds have fallen under increased scrutiny for their environmental impact.Name: Ethyl 4-bromobutyrate
