Abstract
(±)-3-(Ethoxycarbonyl)-2-(imidazol-1-yl) propionic acid (IEPA) crystallized in two different forms when recrystallized from absolute ethanol (Form I) or water (Form II), respectively. The single crystal X ray diffraction study of Form II unambiguously established that IEPA yielded a pseudopolymorph with a different crystalline packing when crystallized from water. This behaviour is additionally confirmed by Differential Scanning Calorimetry (DSC) and Thermogravimetry (TG).
