WebDescription générale. Astec ® CHIRALDEX G-TA is the first choice in the Group 1 CSPs (Surface Interactions, Complex Derivatives). This phase has been shown to be the most broadly-selective phase for the pharmaceutical industry, especially for the analysis of chiral intermediates and drug studies in various stages of clinical trials. WebThe suffix describes the nature of the derivatization i.e., G-TA refers to Gamma Trifluororacetylated phase. The most striking characteristic of these phases is that they separate nonaromatic enantiomers including saturated alcohols, amines, carboxylic acids, epoxides, diols, polyols, cyclic, bicyclic, heterocyclic compounds, lactones, amino ...
