一般描述

AmberChrom 1X2 (formerly Dowex 1X2) is an anion exchange resin.

应用

AmberChrom 1X2 chloride form has been used in the purification step for the synthesis of methyl-esterified sialic acid analogs bearing a diazirine photocrosslinker on the N-acyl (C-5) side chain 5-(SiaDAz).
AmberChrom 1X2 chloride form is a strongly basic (type I) anion exchange resin for food & drug processing. it has been used to characterize a dual emission sensing luminescence material for water-dissolved oxygen sensing. AmberChrom ion exchange resin has also been used to demonstrate decontamination of (99g) Tc from spent 99Mo waste solution and recovery of (99g)Tc for research use.
强碱性（I 型）阴离子交换树脂，用于食物和药品加工；符合美国食品药品管理局食品添加剂法规 21 CFR 173.25 的要求。

  5. How can a Dowex type 1 resin in the chloride form be converted to the carbonate form?

    As one might expect, the procedure requires the use of sodium carbonate (Na2CO3).Citation: Journal of Experimental Medicine, 120, 1007-1018 (1965).From page 1011 of that paper:"A 2 mL column of washed Dowex-1X8 200 to 400 mesh, in the chloride form, was converted to the carbonate form by washing with 1 M Na2CO3 until no chloride could be detected in the eluate. It was then washed with distilled water until the pH of the eluate reached neutrality". The simplest test for chloride is to use a dilute silver nitrate solution. If mixing a few drops of the eluate with a few drops of a silver nitrate solution results in a silver chloride precipitate forming, that would an indication that the eluate contains chloride. You could also use a chloride-specific electrode, if you have access to one.
