- Thus Paul Ehrlich's Salvarsan was an arsenic analogue of an azo dye, and the first sulfa, or wonder, drug, Prontosil, was the metabolic product of a red azo dye.
- Nitrite was determined spectrophotometrically upon diazotation and forming of azo dye.
- Orange smoke compositions, for example, are typically based on 50: 50 mixtures of azo dyes and reactants - a sugar like lactose or sucrose as fuel and an oxidiser such as potassium chlorate.
- The products from these reactions are used in the production of an important class of dyes, the azo dyes.
