Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Predicted low potential of bioconcentration for 5-methoxy-2-methylsulphanilic acid.
Key value for chemical safety assessment
- BCF (aquatic species):
- 3.162 L/kg ww
Additional information
Low potential of bioconcentration is predicted for 5-methoxy-2-methylsulphanilic acid by BCFBAF v.3.01 (log BCF = 0.5; BCF = 3.162 l/kg wet-wt).
To support this predicted value we consider a compound with similar structure, 4-aminotoluene-3-sulfonic acid. As reported in SIDS Dossier of 4-aminotoluene-3-sulfonic acid approved at SIAM 16 (27 -30 May 2003) with reference to METI JAPAN, Biodegradation and bioaccumulation data of existing chemicals based on the CSCL Japan,1992, 4-aminotoluene-3-sulfonic acid shows low bioaccumulation characteristics (BCF < 4 at low concentration-0.2 mg/l- and BCF < 0.4 at high concentration-2 mg/l). The test was performed on Cyprinus carpio according to OECD 305 C.

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).
