[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.
