2-Nitro-p-cresol Usage And Synthesis
| Chemical Properties | yellow to brownish low melting crystalline mass |
| Uses | Intermediate. |
| Uses | 4-Methyl-2-nitrophenol is used to characterize secondary organic aerosols from photooxidation of toluene in hydrocarbon-NOx mixture. |
| Production Methods | p-Toluidine is diazotized andhydrolyzed to p-cresol, which in the presenceof nitrous acid forms 2-nitroso-p-cresol; thelatter is readily oxidized in situ to 2-Nitro-p-cresol by additionof aqueous nitric acid. |
| Hazard | Toxic by ingestion, inhalation, and skinabsorption. |
