Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 27825-21-4, name is Methyl 3-chloropyrazine-2-carboxylate, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 27825-21-4
[577] Step A: 3-mercapto-pyrazine-2-carboxylic acid methyl ester [578] After 3-chloro-pyrazine-2-carboxylic acid methyl ester (0.4 g, 2.3 mmol)was dissolved in MeOH (46 mL), sodium hydrosulfide monohydrate (0.65 g, 6.9mmol) was added thereto, and the mixture was stirred at room temperature for 9hours. After the termination of the reaction, the reactant was concentratedunder reduced pressure, and 1N HCl aqueous solution was used to adjust the pHof the reactant to 3. The reactant was extracted with EtOAc, and the organiclayer was separated to obtain the title compound (0.35 g, 89%).[579] 1H-NMR (CDCl3) delta 8.43(1H, m), 8.42(1H, m),5.18(1H, brs), 4.04(3H, s)
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 27825-21-4.
