Two novel cationic softener containing mono-s-chloro triazinyl reactive dyes together with their analogues were designed. The dyes were synthesized via reacting an N,N-dimethyldodecylamine with p-nitrobenzyl bromide. The resultant was reduced using stannous chloride and hydrochloric acid to produce the primary amine. The quaternary ammonium salt containing primary amine was then diazotized to produce diazonium salt part of azo dye. The diazonium salt was then coupled to H-acid/J-acid reacted with cyanuric chloride and sulfanilic acid. The analogue dyes were prepared via the same route without quaternary ammonium salt making stage. The chemical structures of the novel dyes were characterized by FTIR, H-1-NMR, and elemental analysis. The spectroscopic properties of the dyes were determined in terms of lambda (max) and E > (max) in aqueous solution.
