The disposition of 2,4-dinitroaniline was studied in rats. Male Fisher 344 rats were administered 0 to 90.0 umol/kg (14)C labeled 2,4-dinitroaniline orally or 10.0 umol/kg intravenously. Urine, feces, and bile samples from cannulated rats were analyzed for (14)C activity up to 3 days after pretreatment. Selected rats were killed between 15 minutes and 3 days after dosing and the tissue distribution of 2,4-dinitroaniline was determined. Urine and bile samples were analyzed for metabolites. 2,4-Dinitroaniline was rapidly distributed to all major tissues. Muscle, skin, and adipose tissue contained 65 to 70% of the (14)C activity in the body during the 45 minutes after dosing. Clearance from all tissues was rapid, approximately 70 to 85% of the doses being cleared from most tissues within 6 hours after administration. Three days after administration the major tissues contained very low concentrations of (14)C and variations with dose and route of administration were minimal. Urinary excretion of (14)C activity accounted for 30% of the doses after 6 hours and 63% after 24 hours. Fecal excretion over 3 days accounted for 23% of the dose. Elimination of 2,4-dinitroaniline derived (14)C activity in the bile amounted to 12.5% of the dose after 5 hours. Nine metabolites were detected. 2,4-Dinitrophenylhydroxylamine was the main metabolite. 2,4-Dinitrophenylhydroxylamine was excreted in the urine as the sulfate conjugate and in bile as the glucuronide. /It was/ concluded that 2,4-dinitroaniline appears to have little potential for bioaccumulation in animal tissues. Amine hydroxylation and sulfation of 2,4-dinitroaniline are probable detoxification processes that occur rapidly and facilitate clearance.

2,4-Dinitroaniline at an initial concn of 100 ppm showed no biodegradation in river and sea water after 3 days using a cultivation test method(1).
Based on an estimated log Kow of 1.84(2), the bioconcentration factor (BCF) for 2,4-dinitroaniline can be estimated to be about 15 from a recommended regression-derived equation(1,SRC). This BCF value suggests that bioconcentration in aquatic organisms may not be significant(SRC).
Aromatic amines have been observed to undergo rapid and reversible covalent bonding with humic materials in aqueous solution; the initial bonding reaction is followed by a slower and much less reversible reaction believed to represent the addition of the amine to quinoidal structures followed by oxidation of the product to give an amino-substituted quinone; these processes represent pathways by which aromatic amines may be converted to latent forms in the biosphere(3). In the absence of covalent bonding, a Koc of approximately 240 can be estimated for 2,4-dinitroaniline based on an estimated log Kow of 1.84(2) and a recommended regression-derived equation(1,SRC); this Koc value suggests medium soil mobility(4).

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.
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.
