HPLC purification and separation of 5,5'-substituted-2,4-imidazolidinedithiones.
Several 5,5'-substituted-2,4-imidazolidinedithiones, synthesized from aldehydes or ketones, have been purified by HPLC using poly(styrene-divinylbenzene) packings. Purified 5,5'-substituted-2,4-imidazolidinedithiones have been identified in column effluent by UV absorbance and corroborated by mass spectrometry. Several silica-based, polymeric, and poly(styrene-divinylbenzene)-based packings were evaluated as matrices for resolution of a mixture of purified 5,5'-substituted-2,4-imidazolidinedithiones.
