Description of key information
Bioaccumulation: aquatic/sediments:
Using BCFBAF Program (v3.00) model of EPI suite 2017 the estimated bio concentration factor (BCF) for 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium (CAS No. 94158-82-4) is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium is non bioaccumulative in food chain.
Additional information
Bioaccumulation: aquatic/sediments:
Results of two different predicted data study for the target chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium (CAS No. 94158-82-4) were reviewed for the bioaccumulation end point which are summarized as below:
In a first prediction done by using BCFBAF Program (v3.00) model of EPI suite(Estimation Program Interface 2017) the estimated bio concentration factor (BCF) for 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium (CAS No. 94158-82-4) is 3.162 L/kg wet-wt at 25 deg. c which does not exceed the bioconcentration threshold of 2000. Therefore it is concluded that test chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium is non bioaccumulative in food chain.
In a supporting study another prediction done by using Adsorption Coefficient module (v12.1.0.50374) program of (ACD (Advanced Chemistry Development)/I-Lab predictive module, 2017)
Bio-concentration Factor at range pH 1-14 of the chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium (CAS no. 94158-82-4) estimated to be 1.0 dimensionless. This value indicates that the chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium is non-bioaccumulative in aquatic organisms as this value does not exceed 2000 criteria.
On the basis of above results for target chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium (CAS No. 94158-82-4) (From EPI suite and ACD labs, 2017) it can be concluded that the BCF value of test substance 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium ranges from 1.0 to 3.162 which does not exceed the bioconcentration threshold of 2000, indicating that the chemical 2-amino-4-acetamido-5-[(E)-2-(4-{[2-(sulfooxy)ethane]sulfonyl}phenyl)diazen-1-yl]benzoic acid sodium is not expected to bioaccumulate in the food chain.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
