Thirteen hot brand reactive dyes have been prepared by coupling diazotized 4,4'-methylene bis-o-flouro aniline with various anilino cyanurated coupling components and their dyeing performance on silk, wool and viscose rayon has been assessed. All the dyes gave maroon shades with very good depth and levelness on each fibres. The purity of dyes was checked by thin-layer chromatography. The IR spectra showed all characteristic bands and PMR spectra showed all the signals. The percentage dye bath exhaustion and fixation on different fibres were reasonable good and acceptable. The dyed fibres showed moderate to very good fastness to light, washing and rubbing.
