| Hazard Information | Back Directory | [General Description]
Orange prisms or yellow powder. No odor. | [Reactivity Profile]
Oxidation of this chemical may occur in the presence of air and violent decomposition may occur if 2-AMINO-4-NITROPHENOL(99-57-0) is allowed to dry out completely at elevated temperatures. 2-AMINO-4-NITROPHENOL(99-57-0) 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. This chemical is incompatible with acids, acid chlorides, acid anhydrides, chloroformates and strong oxidizing agents. 2-AMINO-4-NITROPHENOL(99-57-0) is also incompatible with iron. | [Air & Water Reactions]
Insoluble in water. | [Fire Hazard]
Flash point data for this chemical are not available. 2-AMINO-4-NITROPHENOL is probably combustible. | [Chemical Properties]
