2-Amino-4-nitrophenol Usage And Synthesis
Chemical PropertiesOCHRE CRYSTALLINE POWDER
UsesAn aromatic constituent found in hair dyes and other cosmetic products with very low levels of mutagenic activity.
Uses2-Amino-4-nitrophenol is used in preparing some mordant dyes and in some hair dyes.
DefinitionChEBI: 2-Amino-4-nitrophenol is a member of 4-nitrophenols.
Synthesis Reference(s)Organic Syntheses, Coll. Vol. 3, p. 82, 1955
The Journal of Organic Chemistry, 45, p. 4992, 1980 DOI: 10.1021/jo01312a039
General DescriptionOrange prisms or yellow powder. No odor.
Air & Water ReactionsInsoluble in water.
Reactivity ProfileOxidation of 2-Amino-4-nitrophenol may occur in the presence of air and violent decomposition may occur if 2-Amino-4-nitrophenol is allowed to dry out completely at elevated temperatures. 2-Amino-4-nitrophenol is stable when stored protected from light and under nitrogen for two weeks at temperatures up to 140° F, and storage under nitrogen for up to 24 weeks at room temperature (77° F) should produce no loss of stability. 2-Amino-4-nitrophenol is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. 2-Amino-4-nitrophenol is also incompatible with iron.
Fire HazardFlash point data for 2-Amino-4-nitrophenol are not available. 2-Amino-4-nitrophenol is probably combustible.
Flammability and ExplosibilityNon flammable
Purification MethodsCrystallise the phenol from water. [Beilstein 13 IV 896.]
