WebAn HPLC column was prepared with L-Glu chiral silica gel as the stationary phase and n-hexane-isopropanol (9∶1, v/v) as the mobile phase. Fifteen racemic compounds were successfully separated on the chiral HPLC column, including seven racemic compounds for baseline separation, at a flow rate of 0.1 mL/min using 254 nm as the detection ... WebThe chiral resolving ability of the commercially available amylose (3,5-dimethylphenylcarbamate)-based chiral stationary phase (CSP) toward four chiral probes representative of four kinds of stereogenicity (central, axial, helical, and planar) was investigated. Besides chirality, the evident structural feature of selectands is an …
