4-Chloronitrobenzene CAS:100-00-5

4-Chloronitrobenzene is a light yellow monoclinic prisms crystallizes, which are insoluble in water and very soluble in toluene, ether, acetone, or hot ethanol. It is incompatible with strong oxidizers and alkalis. It is extensively used in different industries as an intermediate in the manufacture of dyes, rubber, and agricultural chemicals.

p-Nitrochlorobenzene is a yellow crystalline solid with a sweet odor.

4-Nitrochlorobenzene is an important intermediate in the manufacture of azo dyes and sulfide dyes, the drugs finasteride and paracetamol, the pesticide herbicide, etc. It is also the raw material of rubber antioxidant 4010.

Manufacture of dyes, rubber, and agricultural chemicals

p-Nitrochlorobenzene is largely used to produce p-nitrophenol with smaller production of p-nitroaniline.

Light yellow crystalline solid. Density 1.520 g / cm3. Melting point 83°C. Sweet odor. Very toxic by inhalation, ingestion, and skin absorption. p-Chloronitrobenzene is extensively used in different industries as an intermediate in the manufacture of dyes, rubber, and agricultural chemicals. It is incompatible with strong oxidisers and alkalis.

Confirmed carcinogen with experimental carcinogenic data. A poison by ingestion. Experimental reproductive effects. Mutation data reported. Flammable liquid when exposed to heat, sparks, or flame. May explode on heating. Potentially violent reaction with sodium methoxide. When heated to decomDosition it emits very toxic fumes of NOx and Cl-.

No increase in tumor incidence was seen in rats fed up to 1000 ppm in the diet for 2 years; in mice, results were equivocal, with high-dose animals showing an increase in vascular tumors and low-dose males showing an increase in liver tumors.6 The IARC has determined that there is inadequate evidence in experimental animals and humans for the carcinogenicity of chlorobenzenes.7
