| | 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 and
hydrolyzed to p-cresol, which in the presence
of nitrous acid forms 2-nitroso-p-cresol; the
latter is readily oxidized in situ to 2-Nitro-p-cresol by addition
of aqueous nitric acid. | | Hazard | Toxic by ingestion, inhalation, and skin
absorption. |
