29049085 | [Safety Profile]
Poison by ingestion and
inhalation. It forms methemoglobin in the
body and gves rise to cyanosis and blood
changes. Its effects are cumulative and
analogous to those of nitrobenzene. The
para compound is thought to be somewhat
less toxic than the ortho compound.
Chemically, it is probably converted in the
body to chloroaniline, whch is also
poisonous. In industry, it is the dust of hs
material that is most often the source of
intoxication. Flammable liquid and
dangerous fire hazard when exposed to heat
or flame. It can react with oxidizing
materials. When heated to decomposition it
emits toxic fumes of Cl-, NOx, and
phosgene. See also other

Moist tan or pale yellow crystalline solid | [Definition]
ChEBI: 1-chloro-3-nitrobenzene is a C-nitro compound that is nitrobenzene in which one of the meta- hydrogens has been replaced by chlorine. It is a C-nitro compound and a member of monochlorobenzenes. | [Production Methods]
m-Chloronitrobenzene is of lesser economic importance
than its ortho- and para-isomers, with no U.S. production reported. The annual production in Germany was
reported to be on the order of 1000–3000 metric tons. It
has limited use in the manufacturing of dyes and agricultural
chemicals. There is no information on potential exposure. Chloronitrobenzene
has been detected in the surface water of the
Rhine River with concentrations between 20 and 500 ng/L
and in fish at levels of up to 1 mg/kg. | [Flammability and Explosibility]
Notclassified | [Synthesis]
1-Chloro-3-nitrobenzene was synthesised from 4-chloro-2-nitro-benzoic acid by adding copper iodide, triethylamine and dimethyl sulfoxide in the presence of inert gas using the Schlenk technique.
| [Purification Methods]
Crystallise the nitrobenzene from MeOH or 95% EtOH (charcoal), then pentane. [Beilstein 5 IV 722.] |
