General Description

Brown crystalline solid or powder.

Air & Water Reactions

4-Chloro-1,2-diaminobenzene may be sensitive to prolonged exposure to air and light. Insoluble in water.

Reactivity Profile

4-Chloro-1,2-diaminobenzene is incompatible with strong oxidizers. 4-Chloro-1,2-diaminobenzene reacts with alpha-ketoacids to form quinoxalones.

Fire Hazard

Flash point data for 4-Chloro-1,2-diaminobenzene are not available. 4-Chloro-1,2-diaminobenzene is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic and neoplastigenic data. Human mutation data reported. When heated to decomposition it emits toxic fumes of Cland NOx. See also AROMATIC AMINES.

Potential Exposure

This organochlorine material has been patented as a hair dye component. It is believed to be used in production of photographic chemicals. In varying degrees, organochlorines are absorbed from the gut and also by the lung and across the skin.


UN2811 Toxic solids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required. UN3143 Dyes, solid, toxic, n.o.s. or Dye intermediates, solid, toxic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Recrystallise the diamine from pet. ether. [Beilstein 13 IV 68.]


Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Light sensitive. It reacts with alpha-ketoacids to form quinoxalones or benzopyrazines.

Waste Disposal

Disposal of unused product must be undertaken by qualified personnel who are knowledgeable in all applicable regulations and follow all pertinent safety precautions including the use of appropriate protective equipment. For proper handling and disposal, always comply with federal, state, and local regulations.
