Analysis of Antibiotic Dapsone and Related Impurities in Mixed-Mode Chromatography

Separation type: Liquid Chromatography Mixed-mode

Dapsone is an antibiotic used to treat leprosy and acne. Obelisc R was used to analyze dapsone and its impurities. Obelisc R is a tri-modal reversed-phase, cation- and anion-exchange column. Method is compatible with LC/MS and prep chromatography.
