Description

General description

The pentafluorophenylpropyl stationary phase of Ascentis Express F5 provides a stable reversed phase packing with electron-deficient phenyl rings due to the presence of electronegative fluorines.In addition to forming pi-pi and mildly steric interactions, F5 phases also retain compounds by polar interactions. Ascentis Express F5 can be used for basic, acidic, or neutral compounds with alternate selectivity from C18.
