Bhavsar, R. A. published the artcileSynthesis of some trisazo pyrazolone acid dyes and their application on wool and nylon, Computed Properties of 14580-22-4, the publication is Asian Journal of Chemistry (1998), 10(4), 1061-1062, database is CAplus.
Monoazo pyrazolone dyes are very common but trisazo pyrazolone dyes with an arylazo group in position-4 and a second arylazo group at position-4 of the Ph nucleus and a third arylazo group at position-7 of the naphthyl nucleus of H- or γ-acid are not available. In the preparation of the title dyes, an aryldiazonium chloride is coupled in alk. medium with 1-phenyl-3-methyl-5-pyrazolone or 1-(2-chlorophenyl)-3-methyl-5-pyrazolone and the second arylazo group in position-4 of the 1-Ph group is introduced in acidic medium and the third arylazo group in position-7 of the 4-naphthyl group of H- or γ-acid is applied in alk. medium. Light fastness on wool was 4-5 to 5-6 and 3-4 to 5-6 on polyamide. Wash fastness was 3-4 to 4-5 on wool and 2-3 to 3-4 on polyamide.
Asian Journal of Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C10H9ClN2O, Computed Properties of 14580-22-4.
