2-Methyl-5-nitroaniline Chemical Properties,Uses,Production

Chemical Properties

yellow powder

Chemical Properties

5-Nitro-o-toluidine is a yellow, crystalline solid.


ChEBI: A C-nitro compound in which the nitro compound is meta to the amino group and para to the methyl group of o-toluidine.

General Description

Bright yellow powder.

Air & Water Reactions

Insoluble in water. 2-Methyl-5-nitroaniline is sensitive to moisture, light, or prolonged exposure to air.

Reactivity Profile

2-Methyl-5-nitroaniline is incompatible with strong oxidizing agents, acids, acid chlorides, acid anhydrides and chloroformates.

Fire Hazard

Flash point data for 2-Methyl-5-nitroaniline are not available; however, 2-Methyl-5-nitroaniline is probably combustible.

Safety Profile

Confirmed carcinogen with experimental carcinogenic data. Moderately toxic by ingestion. Mutation data reported. Decomposes exothermically when heated to 150℃. When heated to decomposition it emits toxic fumes of NOx. See also NITRO COMPOUNDS OF AROMATIC HYDROCARBONS.

First aid

If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.


UN2660 Nitrotoluidines (mono), Hazard Class: 6.1; Labels: 6.1-Poisonous materials.

Purification Methods

Acetylate the aniline, and the acetyl derivative is crystallised to constant melting point; then hydrolyse it with 70% H2SO4 and the free base is regenerated by treatment with NH3 [Bevan et al. J Chem Soc 4284 1956]. [Beilstein 12 H 844. 12 IV 1807.]


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, acid chlorides; acid anhydrides; chloroformates.

Waste Disposal

Consult with environmental regulatory agencies for guidance on acceptable disposal practices. Generators of waste containing this contaminant (≥100 kg/mo) must conform with EPA regulations governing storage, transportation, treatment, and waste disposal.
