Description of key information
Biodegradation
Biodegradation in water
Biodegradability of 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate (CAS no. 6035-94-5) is predicted using OECD QSAR toolbox version 3.3 with log Kow as the primary descriptor. Test substance undergoes 0.40 % degradation by BOD in 28 days. Thus, based on percentage degradation, the test chemical 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate was estimated to be not readily biodegradable in water.
Biodegradation in water and sediment
Estimation Programs Interface (EPI Suite, 2017) prediction model was run to predict the half-life in water and sediment for the test compound 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate (CAS No. 6035-94-5). If released in to the environment, 5.52 % of the chemical will partition into water according to the Mackay fugacity model level III and the half-life period of test chemical in water is estimated to be 37.5 days (900 hrs). The half-life (60 days estimated by EPI suite) indicates that the chemical is not persistent in water whereas the half-life period of test chemical in sediment is estimated to be 337.5 days (8100 hrs). However, as the percentage release of test chemical into the sediment is 34.7 %, indicates that test chemical is persistent in sediment.
Biodegradation in soil
The half-life period of 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate (CAS No. 6035-94-5) in soil was estimated using Level III Fugacity Model by EPI Suite version 4.1 estimation database (EPI suite, 2017). If released into the environment, 59.8 % of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of test chemical in soil is estimated to be 75 days (1800 hrs). Based on this half-life value of test chemical, it is concluded that the chemical is not persistent in the soil environment.
Bioaccumulation
Bioaccumulation in aquatic /sediment
BCFBAF model (v3.01) of Estimation Programs Interface (EPI Suite, 2017) was used to predict the bioconcentration factor (BCF) of test chemical 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate (CAS No. 6035-94-5). The bioconcentration factor (BCF) of 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate was estimated to be 3.162 L/kg whole body w.w (at 25 deg C) which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate is not expected to bioaccumulate in the food chain.
Transport and distribution
Adsoption / desorption
The soil adsorption coefficient i.e Koc value of 2-benzylideneheptanal (CAS No. 6035 -94 -5) was estimated to be 124900.0 L/kg (log Koc= 5.0967) by means of MCI method (at 25 deg C). This Koc value indicates that the substance 2-benzylideneheptanal is likely to to show very strong sorption to soil and sediment and show negligible migration to groundwater.

The predicted data of the target chemical is supported by the structurally similar read across 2,2'-ethene-1,2-diylbis(5-aminobenzenesulfonic acid) (CAS: 81 -11 -8) from Japan chemical collaborative knowledge database (J check) 2017, indicates that
Bioaccumulation of 4,4'-diaminostilbene-2,2'-disulphonic acid was analyzed accpording to the OECD Guideline 305 C (Bioaccumulation: Test for the Degree of Bioconcentration in Fish). The test was carried out at nominal concentration of 1st Concentration area: 1 mg/L, 2nd Concentration area: 0.1 mg/L exposed to Cyprinus carpio for 6 wks. The Bioaccumulation factor(BCF) for 2,2'-ethene-1,2-diylbis(5-aminobenzenesulfonic acid (CAS: 81-11-8) is 4.7 L/kg in 6 wk.It can be concluded from the value that the, 2'-ethene-1,2-diylbis(5-aminobenzenesulfonic acid is not bioaccumulative in environment.
