Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

No bioaccumulation is expected

Key value for chemical safety assessment

BCF (aquatic species):
0.5 dimensionless

Additional information

According to the REACH Regulation, Annex IX, column II, the substance does not need to be tested due to the low potential for bioaccumulation (log Kow < 3) and a low potential to cross biological membranes (high molecular weight, high polarity); furthermore direct and indirect exposure of the aquatic compartment is unsuitable.

The Bioconcentration Factor (BCF) value was calculated using BCFBAF v3.01 tool, an application contained in the EpiSuite 4.1 [1], using the following smile notation: O=S(=O)(O)c1cccc(c1)Nc2nc(nc(NCCO)n2)Nc6ccc(/C=C/c3ccc(cc3S(=O)(=O)O)Nc4nc(nc(NCCO)n4)Nc5cccc(c5)S(=O)(=O)O)c(c6)S(=O)(=O)O

The BCF estimated value from regression-based method is 0.500 (BCF = 3.162 L/kg wet-wt), in agreement with the common value of non bioaccumulative substances.
