Nicotinamide is the amide form of nicotinic acid. Nicotinic acid is in the vitamin B group and is converted to nicotinamide in vivo. Newcrom AH was used to separate nicotinamide and nicotinic acid. Newcrom AH separates acids using ion-exclusion, retains basic compounds by cation-exchange, and neutral compounds by reverse-phase mechanism.

Application Column
Newcrom AH
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
