Safety Profile
A poison by intraperitoneal route. Low toxicity by ingestion. When heated to decomposition it emits toxic vapors of NOx and SOx.
Specification
Direct Brown 2 (CAS NO.2429-82-5) is a reddish-brown solid or dark brown powder. Azo dyes can be explosive when suspended in air at specific concentrations. It is slightly soluble in water. It 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. However, It is probably combustible.
