Abstract: Monosubstitute thiazolyl amines were diazotized in acetic acid, coupled to 1-phenyl3-aminopyrazol-5-one (1a-1c) and acetylated to obtain the 2a-2c dyes. The dyes were characterized by elemental analysis and spectroscopic (Fourier transform infrared (FTIR), nuclear magnetic resonance… read more here.
