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.
Synthesis Reference(s)	Organic Syntheses, Coll. Vol. 3, p. 82, 1955The 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.]
