## Abstract A novel chiral stationary phase (CSP) for HPLC was prepared by bonding (__R__)โ€1โ€phenylโ€2โ€(4โ€methylphenyl)ethylamine amide derivative of (__S__)โ€valine to aminopropyl silica gel through a 2โ€aminoโ€3,5โ€dinitroโ€1โ€carboxamidoโ€benzene unit. The CSP was used for the separation of some amino a
