1321-12-6 Usage
Description
Nitrotoluene is an organic compound that exists in three isomeric forms, namely ortho-nitrotoluene, meta-nitrotoluene, and para-nitrotoluene. It is characterized by its weak aromatic odor and can be found as a yellow solid crystal or liquid. Nitrotoluene has a melting point ranging from 32 to 59°F, is insoluble in water, and soluble in alcohol. It is denser than water and is toxic by ingestion, inhalation, or skin contact. The flash point of nitrotoluene is 223°F, and its boiling point is 428°F. During combustion, it produces toxic oxides of nitrogen.

Air & Water Reactions
Insoluble in water.
Reactivity Profile
p-NITROTOLUENE and sulfuric acid explode at 80°C [Chem. Eng. News 27:2504]. Many explosions have occurred in the distillation of nitrotoluene owing to its heat sensitivity. May become unstable in the presence of strong bases.
Health Hazard
Highly toxic, may be fatal if inhaled, swallowed or absorbed through skin. 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.
Fire Hazard
Combustible material: may burn but does not ignite readily. Containers may explode when heated. Runoff may pollute waterways. Substance may be transported in a molten form.
Safety Profile
A poison. May decomposeexplosively if heated above 190°C. When heated todecomposition it emits toxic fumes of NOx.
Potential Exposure
The nitrotoluenes are used in the
production of toluidines and other dye intermediates.
All isomers are used in manufacture of agriculture and
rubber chemicals and in various dyes.
Shipping
UN1664 Nitrotoluenes, (o-; m-; p-), Hazard
Class: 6.1; Labels: 6.1-Poisonous materials.
Incompatibilities
Decomposes on contact with strong oxidizers;
strong acids; reducing agents; strong bases; ammonia,
amines producing toxic fumes, causing fire and explosion
hazard. Heat above 190C may cause explosive decomposition.
Attacks some plastics, rubbers, and coatings.
Waste Disposal
Controlled incineration-care
must be taken to maintain complete combustion at all
times. Incineration of large quantities may require scrubbers
to control the emission of nitrogen oxides.
Check Digit Verification of cas no
The CAS Registry Mumber 1321-12-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,3,2 and 1 respectively; the second part has 2 digits, 1 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 1321-12:
(6*1)+(5*3)+(4*2)+(3*1)+(2*1)+(1*2)=36
36 % 10 = 6
So 1321-12-6 is a valid CAS Registry Number.
