Possibility of hazardous reactions

IN CONTACT WITH OPEN FLAME IN GLASS TUBE OR BEAKER, IGNITES RAPIDLY & BURNS RELATIVELY FAST...2-AMINO-4,6-DINITROPHENOL should not be subjected to strong shock or heat, and is a dangerous fire risk. This compound reacts with strong oxidizing agents. (NTP, 1992). Explodes if dried and exposed to heat, flame, friction or shock. Wetting greatly reduces this tendency. Treat as an explosive. Mixing with reducing agents, including hydrides, sulfides, nitrides, and alkali metals may lead to a vigorous reaction that culminates in a detonation. May explode in the presence of a base such as sodium hydroxide or potassium hydroxide, even in the presence of water or organic solvents. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. An amino acid (reacts as an acid with bases and as a base with acids).

Bioaccumulative potential

A BCF value of 42 was reported for 4,6-dinitro-2-aminophenol in rainbow trout(1). According to a classification scheme(2), this BCF value suggests that bioconcentration in aquatic organisms is moderate.

Mobility in soil

The Koc of 4,6-dinitro-2-aminophenol is estimated as approximately 75(SRC), from its log Kow of 0.93(1) and a regression derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that 4,6-dinitro-2-aminophenol is expected to have high mobility in soil.

Other adverse effects

no data available

SECTION 13: Disposal considerations

Disposal methods


The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Contaminated packaging

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
