| Abstract | ||||
| A sensitive, highly selective and stability indicating procedure for the determination of nicotinamide in some multi-vitamin preparations is described. The procedure is based on thin-layer chromatographic separation of nicotinamide from other constituents of the dosage form, the reaction with aniline and cyanogen bromide vapours, and spectrodensitometric determination at 468 nm. The method is suitable for content uniformity studies. | ||||
