2-Amino-5-methylpyridine is a chemical compound that belongs to the group of methyl ketones. It has a nitrogen atom and an oxygen atom in its structure, which allows it to form hydrogen bonds with other molecules. 2-Amino-5-methylpyridine can be obtained by reacting hydrochloric acid and xanthone in the presence of a base. The compound is highly reactive and has been shown to have antiinflammatory properties. This can be attributed to its ability to inhibit prostaglandin synthesis. 2-Amino-5-methylpyridine also has fluorescence properties that are sensitive to pH changes and can be used as a probe for metal ions. 2-Amino-5-methylpyridine is an organic compound that contains a methyl group, two nitrogen atoms, and one oxygen atom in its chemical structure. This molecule can form hydrogen bonds with other molecules due to its nitrogen atoms and oxygen atom,, 1603-41-4.

Yamaguchi, Koji;Miyaguchi, Hajime;Hirakawa, Keiko;Ohno, Youkichi;Kanawaku, Yoshimasa research published 《 Qualitative analysis of zolpidem and its metabolites M-1 to M-4 in human blood and urine using liquid chromatography-tandem mass spectrometry》, the research content is summarized as follows. The aim of this study was to develop the method for the qual. anal. of zolpidem and its metabolites M-1 to M-4 using liquid chromatog.-tandem mass spectrometry (LC-MS/MS) in human blood and urine. To obtain anal. standards, a method for synthesizing zolpidem metabolites M-1 to M-4 was developed. A combination of a copper-catalyzed three-component coupling reaction and pyrrolidine-catalyzed imine formation was adopted to synthesize the Me esters of M-1 (M-1-Me) and M-2 (M-2-Me), which were hydrolyzed to afford M-1 and M-2, resp. M-3 and M-4 were also synthesized. The LC-MS/MS conditions were optimized using authentic standards M-1 to M-4 were analyzed in human blood and urine. M-1 to M-4 were successfully synthesized. The mass spectra of M-1 and M-2 were almost identical, but their peaks were chromatog. separated using a octadecyl silica column. Likewise, mass spectra of M-3 and M-4 were similar, but their peaks were chromatog. separated The peak intensities of the metabolites in human blood and urine were M-1 > M-2, and M-4 > M-3; M-3 was detected only in urine. The presence of other hydroxyzolpidems was also revealed. Chromatog. separation of M-1 and M-2 and that of M-4 and other hydroxyzolpidems is necessary to analyze zolpidem metabolites in biol. matrixes because their mass spectra are quite similar. This study is the first to analyze zolpidem and M-1 to M-4 simultaneously using LC-MS/MS, which can provide more compelling evidence of zolpidem intake.
