What is Pigment Yellow 74?

General Description

Bright yellow powder. Considerable change and tendency to sublime when heated to melting point.

Air & Water Reactions

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

Reactivity Profile

Pigment Yellow 74 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.

Fire Hazard

Flash point data for Pigment Yellow 74 are not available. Pigment Yellow 74 is probably combustible.
