The synthesis and application of azo dyes derived from 2-amino 5-mercapto 1, 3, 4 – thiadiazole on polyester fiber are described. These dyes were characterized by IR spectra, 1H – NMR spectra and elemental analysis. The dyed fiber showed good to excellent fastness properties. The dye bath exhaustion and fixation on polyester fiber was found to be very good.
