In aqueous solution at low pH, methyl yellow appears red. Between pH 2.9 and 4.0, methyl yellow undergoes a transition, to become yellow above pH 4.0. As "butter yellow" the agent had been used as a food additive before its toxicity was recognized (Opie EL). 4-(Dimethylamino)azobenzene 4-(Dimethylamino)phenylazobenzene 4-(N,N-Dimethylamino)azobenzene 4-(Phenylazo)-N,N-dimethylaniline Butter yellow C.I. 11020 C.I.
