2-Nitroaniline is the main precursor to phenylenediamines, which are converted to benzimidazoles, a family of heterocycles that are key components in pharmaceuticals. [ 2 ] Intramolecular hydrogen-bonding results in a very low basicity for 2-nitroaniline.
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-Methoxy-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 3 (OCH 3)NH 2. [2] It is one of four isomers of methoxynitroaniline. The compound is a precursor to the commercial Pigment Yellow 74.
An example of inorganic nitroamine is chloronitroamine, Cl−NH−NO 2. [3] The parent inorganic compound, where both R substituents are hydrogen, is nitramide or nitroamine, H 2 N−NO 2. N-Nitroaniline rearranges in the presence of acid to give 2-nitroaniline. [4]
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]
2,4,6-Trinitroaniline, C 6 H 4 N 4 O 6, abbreviated as TNA and also known as picramide, a nitrated amine. Materials in this group range from slight to strong oxidizing agents . If mixed with reducing agents , including hydrides , sulfides and nitrides , they may begin a vigorous reaction that culminates in a detonation.

2,6-Dichloro-4-nitroaniline is an organic compound with the formula O 2 NC 6 H 2 Cl 2 NH 2. It is the most widely discussed isomer of dichloronitroaniline, mainly as a precursor to the azo dye disperse brown 1. It is prepared by treatment of 4-nitroaniline with a mixture of hydrochloric acid and hydrogen peroxide (a source of chlorine). [3] [4]
