PH. EUR. 2002 identifies nicotinamid, nicotinic acid, and nikethamide according the reaction of König using cyanogen bromide solution prepared with bromine water and ammonium thiocyanate immediately before use. This colour reaction can be better performed with 1,3-dibromo-5,5-dimethylhydantoin (DBH) and sulphanilic
