Description and Uses
4-N,N-Dimethylaminobenzene diazonium chloride is a diazo compound found in diazo copy paper. It is allergenic only when unexposed.
Butter yellow was largely used as a food coloring agent. It was also used for the determination of free hydrochloric acid in gastric juice, for the spot test identification of peroxidized fats, as a pH indicator, and as a laboratory reagent.
