Synthetic Route of 1072-67-9, Catalysts function by providing an alternate reaction mechanism that has a lower activation energy than would be found in the absence of the catalyst. In some cases, the catalyzed mechanism may include additional steps.In a article, 1072-67-9, molcular formula is C4H6N2O, introducing its new discovery.
Stable isotope-labeled sulfamethoxazole and synthesis method thereof (by machine translation)
The invention discloses a stable isotope-labeled sulfamethoxazole and a synthesis method. S1: reacting stable isotope-labeled acetaminophen with chlorosulfonic acid, preparing a stable isotope-labeled p-acetyl aminobenzyl chloride; S2: reacting the stable isotope-labeled acetaminophenylsulfonyl, 3 – amino -5 methylisoxazole and 4 4-dimethylaminopyridine with a stable isotope label. S3: reacting the stable isotope-labeled acetaminophthyl chloride with chlorosulfonic acid to obtain a stable isotope-labeled p-acetyl aminobenzyl chloride. The stable isotope-labeled sulfamethoxazole; S4: the stable isotope-labeled sulfamethoxazole is hydrolyzed under basic conditions to prepare the stable isotope-labeled sulfamethoxazole. The synthesis process is simple, the product is easy to separate and purify, the obtained product has good chemical purity and 99% isotopic abundance, and meets the requirements of standard reagents for quantitatively detecting sulfamethoxazole; the using value is high, and the economic.
