Applicazioni
Dowex 1X4, anion-exchange resin was used as adsorbent material in characterization of iodinated contrast media using 11B NMR and capillary electrophoresis.[1] The unreacted fluoride in a solution was removed by passing the solution through a column packed with Dowex 1X4-50 chloride form.[2]
Strongly basic (type I) anion exchange resin for fine pharmaceuticals; meets requirements of FDA Food Additive Regulation 21 CFR 173.25.
Caratteristiche e vantaggi
strongly basic anion.

We report on the preparation of a hypoxia marker 2-(2-nitroimidazol-1[H]-yl)-N-(3-fluoropropyl)acetamide (EF1) and its 18F analog, 2-(2-nitroimidazol-1[H]-yl)-N- (3-[18F]fluoropropyl)acetamide ([18F]-EF1). Two methods for the preparation of 3-fluoropropylamine, the EF1 side chain, are described. [18F]-EF1 was prepared with a radiochemical yield of 2%

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