WebAvoid racemic mixtures by using chirally pure starting materials (synthons), asymmetric synthesis, chemical catalysis or biocatalysis. (2) Post-synthetically using chromatography. Chiral stationary phases (HPLC and SFC) can separate racemic mixtures into the individual isomers and can be scaled-up to preparative sizes. WebDec 15, 2024 · This is because of the special property of hand, that is called chirality. Both left and right hand are chiral (ky-ral), and show chirality. Chiral derived from the Greek word cheir, that means “hand”, and chirality means “handedness”. Figure 5.3a Left hand and right hand are non-superimposable mirror images. The definition of the ...
