What is 2-Methyl-3-nitroaniline?

Chemical properties

YELLOW TO GREENISH-YELLOW CRYSTALLINE POWDER

The Uses of 2-Methyl-3-nitroaniline

2-Amino-6-nitrotoluene (2-Methyl-3-nitroaniline) has been used as a standard while evaluating the potential for degradation of nitroaromatic compounds by indigenous microorganisms.

Production Methods

6-Nitro-o-toluidine is produced by sulfide reduction of 2,6-dinitrotoluene in a process similar to that for 3-nitroaniline or by controlled hydrogenation of 2,6-dinitrotoluene with palladium on a carbon catalyst.

General Description

Yellow rhombic needles (from water) or bright yellow powder.

Air & Water Reactions

2-Methyl-3-nitroaniline may be sensitive to prolonged exposure to air. Insoluble in water.

Reactivity Profile

2-Methyl-3-nitroaniline is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizers.

Fire Hazard

Flash point data for 2-Methyl-3-nitroaniline are not available; however, 2-Methyl-3-nitroaniline is probably combustible.

Purification Methods

Crystallise the nitrotoluidine from EtOH or *C6H6. It is steam volatile. The acetyl derivative crystallises from aqueous EtOH and has m 164o. [Beilstein 12 I 395, 12 II 460, 12 III 1944, 2 IV 1811.]
