Separation of Nicotinamide and Related Substances

A complex mixture of nicotinamide and related impurities was separated on Obelisc R mixed-mode column. Nicotinamide, methylnicotinamide, nicotinamide adenine mononucleotide, nicotinamide adenine dinucleotide, and adenosine monophosphate were baseline resolved in a 15 minute long method. This mixed-mode approach can be used for analysis of other nucleotides. Obelisc R trimodal column separates this complex mixture based on reversed-phase, cation-exchange and anion-exchange mechanisms. Retention is controlled by amount of ACN, buffer concentration and buffer pH. Additional selectivity can be gained by exploring various buffers within the same pH
