Pigment Red 2 Chemical Properties,Usage,Production
Chemical Properties yellowish red or dark red powder
General Description Yellowish red solid with a tint of pink or dark red powder.
Air & Water Reactions Azo dyes can be explosive when suspended in air at specific concentrations. Insoluble in water.
Reactivity Profile Pigment Red 2 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 Red 2 are not available, however Pigment Red 2 is probably combustible.
