    3-Nitroaniline, also known as 'meta'-nitroaniline and m-nitroaniline, is a non-volatile stable solid commonly used as a raw material for dyes. 3-Nitroaniline is an aniline carrying a nitro functional group in position 3. It is stable in neutral, acidic or alkaline solutions and is classified as "not readily biodegradable" with "low bioaccumulation potential" .
    It is used as a chemical intermediate for azo coupling component 17 and the dyes disperse yellow 5 and acid blue 29. The chemical is changed to other substances (dyestuffs and m-nitrophenol) during the dyeing process.

    • Toxicity to algae: no data available
    • Toxicity to microorganisms: no data available

    12.2 Persistence and degradability

    AEROBIC: The mono-nitroanilines were found to be markedly more resistant to biological degradation, as compared to aniline, using Warburg respirometer procedures(1). 3-Nitroaniline was determined to be non-biodegradable using the Japanese MITI protocol(2). No biodegradation of 3-nitroaniline (100 ppm) was observed in a 2-week period in the standard biodegradability test of the Japanese Ministry International Trade and Industry (MITI), a BOD test utilizing a mixed inoculum of activated sludge, sewage and surface water(3). No biodegradation of 3-nitroaniline was observed at concn of 25-30 ppm upon incubation with adapted activated sludge for 20 days(4). No degradation of 3-nitroaniline in a mineral salts solution, with a soil inoculum, occurred in 64 days(5). No biodegradation occurred over a 240 hr period in a respirometer study(6). Only limited biooxidation of 3-nitroaniline was observed in respirometric tests utilizing phenol-adapted bacteria(7). In a 60-day respirimeter test using sewage seed, no biodegradation of 3-nitroaniline (5 ppm) occured(8). However partial degradation was observed when the test solution was cross-seeded with microorganisms acclimated to 4-nitroaniline(8). Using the Zahn-Wellens test procedure, 3-nitroaniline was difficult to degrade as elimination was less than 20% over the 28 day incubation period(9). In another Zahn-Wellens test, no DOC removal occurred in 23 days of incubation(10). 3-Nitroaniline had a biodegradation rate of 0.026/h in river water giving a half-life of 27 hours, which was classified as poor degradation(11). A 5 day BOD at 20°C in Songhua river water was 6% for 3-nitroaniline(12).

    12.3 Bioaccumulative potential

    A 6-week bioconcentration study in carp obtained BCF values of 1.1-3.0 and <10 for concentrations of 3- nitroaniline of 0.5 and 0.05 mg/L, respectively(1). An aquarium study using carp fish found 3-nitroaniline to have a low bioaccumulation potential(2). A study using zebrafish experimentally determined the BCF for 3-nitroaniline to be 8.3(3). According to a classification scheme(4), these BCF values suggest bioconcentration in aquatic organisms is low(SRC).

    12.4 Mobility in soil

    Soil adsorption studies using four silt loam soils and a 2-hour adsorption period determined a mean log Kom of 1.70 which corresponds to a Koc of 87 for 3-nitroaniline(1). 3-Nitroaniline had a measured log Koc of 1.64 which corresponds to a Koc value of 44(2). According to a classification scheme(3), these Koc values suggest that 3-nitroaniline is expected to have very high to high mobility in soil(SRC). 3-Nitroaniline was found to have a Kd value of 3.5 L/kg in homoionic K+ Montmorillonite type soil(4). However, anilines are expected to bind strongly to humus or organic matter in soils due to the high reactivity of the aromatic amino group(5,6), suggesting that mobility may be much lower in some soils(SRC).

    12.5 Other adverse effects

    no data available

    13.Disposal considerations

    13.1 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.
