| Abstract：carboxyphenylhydrazine-5-sulfonic acid was synthesized through diazotization and reduction of 2-amino-4-sulfobenzoic acid, and then condensed with benzaldehyde to obtain 2-\[(phenylmethylene)- hydrazino\]-4-sulfobenzoic acid. The total yield is about 90%. The product structure was confirmed by H~(1)NMR and MS. |
