WebCHIRALDEX™ G-TA is one of the top choices for the analysis of Group 1 CSPs (Surface Interactions, Complex Derivatives). It 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. WebG-TA has its highest selectivity for oxygen-containing analytes like alcohols, diols and polyols as the free alcohol and as an acyl derivative; amines as acyl derivatives; amino alcohols, halogens (Cl>Br>F), amino acids, hydroxy acids, lactones, furans and pyrans. It is also highly selective for halogenated compounds. Astec® CHIRALDEX® G-TA ...
