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	Nonflammable
Purification Methods	Crystallise the phenol from water. [Beilstein 13 IV 896.]
