What are the applications of Application

Disperse Yellow 3 is a small molecule azo dye compound

Definition

ChEBI: An azo dye with a structure consisting of acetanilide substituted on the 4-position of the phenyl group with a 6-hydroxy-m-tolylazo group.

Preparation

N-(4-aminophenyl)acetamide diazo, and to a p-Cresol?coupling

General Description

Brownish-yellow powder.

Air & Water Reactions

Azo dyes can be explosive when suspended in air at certain concentrations. Insoluble in water.

Reactivity Profile

Disperse Yellow 3 is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides. Disperse Yellow 3 is incompatible with strong oxidizing agents and strong acids .

Fire Hazard
