Description of key information
Biodegradation in water
Estimation Programs Interface Suite (EPI suite, 2017) was run to predict the biodegradation potential of the test compound (3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid(CAS no. 3244 -88 -0) in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Timeframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that chemical3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acidis expected to be not readily biodegradable.

The results indicate that chemical3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acidis expected to be not readily biodegradable.
Biodegradation in soil
The half-life period of3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid(CAS No.3244 -88 -0) 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,37.3 % of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of
3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid in soil is estimated to be 120 days (2880 hrs). Based on this half-life value of3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1 -(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid, it is concluded that the chemical is not persistentin the soi
Additional information
Biodegradation in water
Different studies includes the predicted data for the target chemical and exeprimental study of structurally similar read across to conclude the biodegradation in water is summarized as follows:
Estimation Programs Interface Suite (EPI suite, 2017) was run to predict the biodegradation potential of the test compound (3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid(CAS no. 3244 -88 -0) in the presence of mixed populations of environmental microorganisms. The biodegradability of the substance was calculated using seven different models such as Linear Model, Non-Linear Model, Ultimate Biodegradation Tieframe, Primary Biodegradation Timeframe, MITI Linear Model, MITI Non-Linear Model and Anaerobic Model (called as Biowin 1-7, respectively) of the BIOWIN v4.10 software. The results indicate that chemical3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acidis expected to be not readily biodegradable.
The above predicted data of target chemical is supported by theexeprimental study of structurally similar read across
2, 2'-ethene-1,2-diylbis(5-aminobenzenesulfonic acid) ( CAS no. 81-11-8) from J-CHeck 2017 suggests that The test chemical 2, 2'-ethene-1,2-diylbis(5-aminobenzenesulfonic acid) ( CAS no. 81-11-8) was subjected to biodegradation test by taking sludge as a inoculums at 30 mg/L concentration . Biodegradation was analysed by using two parameters BOD and HPLC. The initial concentration of test chemical was 100 mg/L and study design is of standard type. After 4 weeks( 28 days) test chemical showed 0% and 2 % biodegradation by BOD and HPLC parameters respectively so it is concluded that it is not readily biodegradable.
On the basis of above results for target chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (from EPI suite) and for its read across chemical (from J-CHeck 201) it can be concluded that the chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate is not 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 3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid (CAS No.3244-88-0). If released in to the environment, 2.2 % of the chemical will partition into water according to the Mackay fugacity model level III and the half-life period of3-(1-(4 -amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid (CAS No.3244-88-0)in water is estimated to be 60 days (1440 hrs). The half-life (60 days estimated by EPI suite) indicates that the chemical is persistent in water. whereas the half-life period of3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid (CAS No.3244-88-0)in sediment is estimated to be 541.6 days (13000 hrs). However, as the percentage release of test chemical into the sediment is greater than 1% (i.e, reported 60.5 %), indicates that3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acidis persistent in sediment.

If released into the environment,37.3 % of the chemical will partition into soil according to the Mackay fugacity model level III. The half-life period of3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid in soil is estimated to be 120 days (2880 hrs). Based on this half-life value of3-(1-(4-amino-3-methyl-5-sulphonatophenyl)-1-(4-amino-3-sulphonatophenyl)methylene)cyclohexa-1,4-dienesulphonic acid, it is concluded that the chemical is not persistentin the soil environment.
