4-Aminoazobenzene-3,4'-disulfonic acid Chemical Properties,Usage,Production

Uses

4-Aminoazobenzene-3,4''-disulfonic Acid is used in the synthesis of novel acid dyes with a coumarin moiety.

Definition

ChEBI: A member of the class of azobenzenes that is azobenzene in which one of the phenyl groups is substituted at the para position by a sulfo group, while the other is substituted at a meta position by a sulfo group and at the pa a position by an amino group. The disodium salt is the biological stain 'fast yellow'.
