The term nitroaniline in chemistry refers to a derivative of aniline (C 6 H 5 NH 2) containing a nitro group (—NO 2) There are three simple nitroanilines of formula C 6 H 4 (NH 2)(NO 2) which differ only in the position of the nitro group: 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline
2-Nitroaniline is an organic compound with the formula H 2 NC 6 H 4 NO 2. It is a derivative of aniline, carrying a nitro functional group in position 2. [1] It is mainly used as a precursor to o-phenylenediamine.
4-Nitroaniline, p-nitroaniline or 1-amino-4-nitrobenzene is an organic compound with the formula C 6 H 6 N 2 O 2. A yellow solid, it is one of three isomers of nitroaniline. It is an intermediate in the production of dyes, antioxidants, pharmaceuticals, gasoline, gum inhibitors, poultry medicines, and as a corrosion inhibitor. [3]
3-Nitroaniline is an organic compound with the formula H 2 NC 6 H 4 NO 2. A yellow solid, it is a derivative of aniline, carrying a nitro functional group in position 3. It is an isomer of 2-nitroaniline and 4-nitroaniline. It is used as a precursor to dyes. [1]
The molecular formula C 6 H 6 N 2 O 2 (molar mass: 138.12 g/mol) may refer to: Nitroanilines. 2-Nitroaniline; 3-Nitroaniline; 4-Nitroaniline;
Aniline (from Portuguese anil 'indigo shrub', and -ine indicating a derived substance) [6] is an organic compound with the formula C 6 H 5 NH 2.Consisting of a phenyl group (−C 6 H 5) attached to an amino group (−NH 2), aniline is the simplest aromatic amine.
Reduction of 1,3-dinitrobenzene with sodium sulfide in aqueous solution leads to 3-nitroaniline. Further reduction with iron and hydrochloric acid (HCl) gives m-phenylenediamine. [2] 1,3-Dinitrobenzene can be nitrated to 1,3,5-trinitrobenzene with nitronium tetrafluoroborate in fluorosulfuric acid at 150 °C. [3] [4]
1,2-Dinitrobenzene is one of three isomers of dinitrobenzene, with the formula C 6 H 4 (NO 2) 2. The compound is a white or colorless solid that is soluble in organic solvents. It is prepared from 2-nitroaniline by diazotization and treatment with sodium nitrite in the presence of a copper catalyst. [1]
