| | 2-Amino-4-nitrophenol Usage And Synthesis |
| Chemical Properties | OCHRE CRYSTALLINE POWDER | | Uses | An aromatic constituent found in hair dyes and other cosmetic products with very low levels of mutagenic activity. | | Uses | 2-Amino-4-nitrophenol is used in preparing some mordant
dyes and in some hair dyes. | | Definition | ChEBI: 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 Description | Orange prisms or yellow powder. No odor. | | Air & Water Reactions | Insoluble in water. | | Reactivity Profile | Oxidation 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 Hazard | Flash point data for 2-Amino-4-nitrophenol are not available. 2-Amino-4-nitrophenol is probably combustible. | | Flammability and Explosibility | Non flammable | | Purification Methods | Crystallise the phenol from water.
