Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.
[1] EpiSuite is the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
