In 1884, H.J. Ziegler first used pyrazolones as coupling components. In an attempt to find a new dye by synthesizing a colored osazone from phenyl hydrazine-4-sulfonic acid and dioxo tartaric acid, he obtained yellow tartrazine by condensation ... [Pg.210]

Tartrazine was separated from the intermediates sulfanilic acid, pyrazolone-T, and phenyl-hydrazine-p-sulfonic acid (PHSA) and from the side reaction products DAADBSA and l-(4-sulfophenyl)-3-ethyl carboxy-5-hydroxypyrazolone (EEPT) by ion-exchange HPLC (199,214). [Pg.559]
