Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

BCFBAF Program (v3.01) Results:

==============================

SMILES : C=CS(=O)(=O)c1ccc(cc1)Nc2nc(CL)nc(n2)Nc3cc(NC(=O)N)c(cc3)N=Nc4cc5c(S(

=O)(=O)O)cc(S(=O)(=O)O)cc5cc4S(=O)(=O)O

CHEM : 1,3,6-Naphthalenetrisulfonic acid, 7-[[2-[(aminocarbonyl)amino]-4-[[4

-chloro-6-[[4-(ethenylsulfonyl)phenyl]amino]-1,3,5

MOL FOR: C28 H22 CL1 N9 O12 S4

MOL WT : 840.23

--------------------------------- BCFBAF v3.01 --------------------------------

Summary Results:

Log BCF (regression-based estimate): 0.50 (BCF = 3.16 L/kg wet-wt)

Biotransformation Half-Life (days) : 0.000514 (normalized to 10 g fish)

Log BAF (Arnot-Gobas upper trophic): -0.02 (BAF = 0.951 L/kg wet-wt)

Log Kow (experimental): not available from database

Log Kow used by BCF estimates: 0.48

Equation Used to Make BCF estimate:

Log BCF = 0.50 (Ionic; Log Kow dependent)

Estimated Log BCF = 0.500 (BCF = 3.162 L/kg wet-wt)

Validity criteria fulfilled:
not specified
Conclusions:
The estimated bioconcentration factor (BCF) for 1,3,6-Naphthalenetrisulfonic acid, 7-((2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)azo)-, sodium salt is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000 L/kg. Thus it is concluded that Benzenamine, N-phenyl-, styrenated is not expected to bioaccumulate in the food chain because it does not exceed the BCF criteria.
Executive summary:

The estimated bioconcentration factor (BCF) for 1,3,6-Naphthalenetrisulfonic acid, 7-((2-((aminocarbonyl)amino)-4-((4-chloro-6-((4-(ethenylsulfonyl)phenyl)amino)-1,3,5-triazin-2-yl)amino)phenyl)azo)-, sodium salt is 3.162 L/kg, that does not exceed the bioconcentration threshold of 2000 L/kg. Thus based on the classification criteria for BCF, it is concluded that the test substance is not expected to bioaccumulate in the food chain.
