| Hazard Information | Back Directory | [General Description]
Yellow needles or mustard yellow powder. | [Reactivity Profile]
2-METHYL-4-NITROANILINE(99-52-5) is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available; however, 2-METHYL-4-NITROANILINE is probably combustible. | [Chemical Properties]
Yellowneedle | [Uses]
2-Methyl-4-nitroaniline was used in preparing in-plane aligned nanofibers by the electrospinning technique. It was the starting reagent in the synthesis of 3-chloro-5-methylphenyl isocyanate. It was used to deposit polycrystalline thin films on Ag, Cu and Si by conventional and partially ionized beam deposition. | [Uses]
A red azoic dye. | [Production Methods]
N-Benzenesulfonyl-o-toluidine is dissolved in chlorobenzene at 40 – 50 ℃, and 62 % nitric acid is added gradually to give 5- nitro-N-benzenesulfonyl-o-toluidine, which is isolated and hydrolyzed in sulfuric acid to give 5-nitro-o-toluidine in 80 % yield. | [Purification Methods]
Crystallise the nitrotoluidine from EtOH. The acetyl and benzoyl derivatives have m 200o and 174o (EtOH) respectively. [Beilstein 12 IV 1809.] |
