Hazard Information

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.
