What is the [OH−] of an aqueous solution with [H3O+] = 9.2 x 10−2M? Self-Ionization of Water: Water can self-ionize into hydronium and hydroxide ions. In this ionization process, two water molecules react with each other so that one molecule acts as an Arrhenius acid ...
氨基酸酯同Cbz-Cl的反应则是在有机溶剂中进行,并用碳酸氢盐或三乙胺来中和反应所产生的HCl。此外,Cbz-ONB(4-O2NC6H4OCOOBn)等苄氧羰基活化酯也可用来作为苄氧羰基的导入试剂,该试剂使伯胺比仲胺易被保护,但苯胺由于亲核性不足,与该试剂不反应[D.R. Kelly, M. Gingell, Chem. Ind.(London) ,1991, ...
First introduced by the French scientist Jean Lugol in 1829, Lugol’s iodine isn't a brand but rather a distinctive formulation of iodine. It comprises an aqueous solution, which simply denotes water as its primary medium, blended with potassium iodide and iodine. This unique combination amplifies...
