Chemistry, Properties & Perfumer Guide

The Chemistry

C.I. Acid Yellow 3 is a synthetic azo dye belonging to the acid dye class, characterized by its sulfonic acid groups which confer water solubility. It is produced through diazotization and coupling reactions typical of azo dye synthesis. The molecular structure features chromophores responsible for its intense yellow color. While not a fragrance compound, its chemical stability makes it suitable for industrial coloration processes where lightfastness is required.
