Heterocyclic compounds can be divided into two categories: alicyclic heterocycles and aromatic heterocycles. Compounds whose heterocycles in the molecular skeleton cannot reflect aromaticity are called alicyclic heterocyclic compounds. Compound: 23307-72-4, is researched, Molecular C10H8ClN4NaO2S, about High-throughput screening of pesticide and veterinary drug residues in baby food by liquid chromatography coupled to quadrupole Orbitrap mass spectrometry, the main research direction is pesticide veterinary drug baby food quadrupole Orbitrap mass spectrometry; Baby food; Multi-residue methods; Q-Orbitrap; Targeted-screening; Validation.Quality Control of Sodium ((4-aminophenyl)sulfonyl)(6-chloropyrazin-2-yl)amide.
A new anal. method was developed and validated for simultaneous anal. of 333 pesticide and veterinary drug residues in baby food. Response surface methodol. was employed to optimize a generic extraction method. Ultrahigh-performance liquid chromatog. and electrospray ionization quadrupole Orbitrap high-resolution mass spectrometry (UHPLC-ESI Q-Orbitrap) was used for the separation and detection of all the analytes. The method was validated by taking into consideration the guidelines specified in Commission Decision 2002/657/EC and SANCO/12571/2013. The extraction recoveries were in a range of 79.8-110.7%, with coefficient of variation <8.3%. The 333 compounds behave dynamic in the range 0.1-1000 μg kg-1 concentration, with correlation coefficient >0.99. The limits of detection for the analytes are in the range 0.01-5.35 μg kg-1. The limits of quantification for the analytes are in the range 0.01-9.27 μg kg-1. This method has been successfully applied on screening of pesticide and veterinary drugs in ninety-three com. baby food samples, and tilmicosin, fenbendazole, tylosin tartrate and thiabendazole were detected in some samples tested in this study. The present study is very useful for fast screening of different food contaminants.
As far as I know, this compound(23307-72-4)Quality Control of Sodium ((4-aminophenyl)sulfonyl)(6-chloropyrazin-2-yl)amide can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
