4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3) belongs to pyrimidine derivatives. Pyrimidine is an aromatic heterocyclic organic compound similar to pyridine. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Synthetic Route of C11H12N4O3S

Screening and Analysis of Multiclass Veterinary Drug Residues in Animal Source Foods using UPLC-Q-Exactive Orbitrap/MS was written by Zhao, Wentao;Jiang, Rui;Guo, Wenping;Guo, Chao;Li, Shilei;Wang, Juanqiang;Wang, Shouwei;Li, Yingying.

A rapid, simple, and sensitive method of detecting veterinary drug residues in animal food sources, including poultry and pork, was developed and validated. The method was optimized for over 155 veterinary drugs of 21 different classes. Sample pretreatment included a simple solid-liquid extraction step with 0.2% formic acid-acetonitrile-water and a purification step with a PRiME HLB (hydrophile-lipophile balance) solid-phase extraction cartridge. Data were collected using ultra-high-performance liquid chromatog. coupled to Quadrupole-Exactive Orbitrap mass spectrometry. The limits of detection of 155 veterinary drugs ranged from 0.1μg/kg to 10μg/kg. The recovery rates were between 79.2 and 118.5% in all matrixes studied, with relative standard deviation values less than 15% (n = 6). The evaluated method allows the reliable screening, quantification, and identification of 155 veterinary drug residues in animal source food and has been successfully applied in authentic samples. In the experiment, the researchers used many compounds, for example, 4-Amino-N-(6-methoxypyrimidin-4-yl)benzenesulfonamide (cas: 1220-83-3Synthetic Route of C11H12N4O3S).
