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.] |
