Estimating chromatographic enantioselectivity (?) from gradient enantioselective chromatography dataXiaoyi Gong
Separation and Purification Center of Excellence, Merck and Co, Inc, Rahway, New Jersey, USA
Chirality 23:128-32. 2011..The algorithm was validated for SFC applications and has been shown to accurately predict enantioselectivity for a wide variety of racemic test analytes eluted on different chiral column and mobile phase conditions...
Simultaneous enantioseparation of a basic active pharmaceutical ingredient compound and its neutral intermediate using reversed phase and normal phase liquid chromatography with a new type of polysaccharide stationary phaseLili Zhou
Merck Research Laboratories, Merck and Co Inc, Rahway, NJ 07065, USA
J Pharm Biomed Anal 51:153-7. 2010..No matrix interference was observed across the elution windows of compound-A and its intermediate. Additionally, the peak purity of each enantiomer was evaluated by mass spectra, indicating the specificity of the method...
