5-Sulphoanthranilic acid was diazotized and coupled with 1-(3'-sulphophenyl)-3-methyl-5-pyrazolone and 1-(phenyl)-3-methyl-5-pyrazolone to give 1-(3'-sulphophenyl)-3-methyl-4-azo(2'-carboxy-4"-sulphonic acid)-5-pyrazolone[MSMACSP] I and 1-(phenyl)-3-methyl-4-azo-(2'-carboxy-4'-sulphonic acid)-5-pyrazolone [PMACSP] II respectively.The metal complexes of I and II with various metal ions have been prepared. The synthetic compounds were characterized by elemental and spectral analysis, and their dyeing properties on wool and nylon fabrics were investigated.
