Direct Determination of Niacinamide in Multivitamin Preparations

Journal of Pharmaceutical Sciences, 1961
Abstract A simple method for the direct determination of niacinamide in pharmaceutical preparations is described. The method involves the reaction of niacinamide in potassium dihydrogen phosphate with cyanogen bromide and barbituric acid. The resulting purple color has a maximum absorbance at 550 m μ . Niacin does not interfere in the reaction unless

Gas-Liquid Chromatography of Niacin and Niacinamide

Journal of Pharmaceutical Sciences, 1968
A procedure has been developed for the qualitative and quantitative determination of niacin and niacinamide by gas-liquid chromatography. Niacin was determined as its ethyl ester (ethyl nicotinate) or as N -ethylnicotinamide. Niacinamide was determined as niacinamide or converted to either ethyl nicotinate or N -ethylnicotinamide. An immobile biphase
