Appearance: Chlorodinitrobenzene (CAS NO.25567-67-3) is a colorless to yellow crystalline solid with an almond-like odor.

A poison by ingestion. Mutation data reported. Potentially explosive. When heated to decomposition it emits very toxic fumes of Cl⁻ and NO_x. See also other chloro-dinitrobenzenes.

DOT Classification:  6.1; Label: Poison

1.General Description : Chlorodinitrobenzene (CAS NO.25567-67-3) is combustible but may be difficult to ignite. Toxic by skin absorption or inhalation (dust, etc.). May spontaneously decompose and explode under prolonged exposure to fire or heat. Produces toxic oxides of nitrogen during combustion.
2.Reactivity Profile :The reaction of 2,4-Dinitrochlorobenzene and hydrazine hydrate is exothermic, chlorodinitrobenzene shattered the reaction flask,
3.Health Hazard :TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.
4.Fire Hazard: Combustible material: may burn but does not ignite readily. When heated, vapors may form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
