Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Study scientifically not necessary.
Key value for chemical safety assessment
Additional information
Hydrolysis can be considered as negligible degradation pathway due to the chemical structure and the functional groups present in the substance: The 5-sulfobenzoic acid contains beside the core part "benzene" a "carboxylic acid", an "alcohol" and a "sulfonic acid" as functional group. All of those structure elements are listed as resistant groups against hydrolysis in Lyman's Handbook of chemical property estimation (Lyman, W J, Reehl, W F, and Rosenblatt, D H. Handbook of chemical property estimation methods. United States: N. p., 1990. Web.). This handbook presents simple estimation methods for 26 important properties of organic chemicals that are of environmental concern. This book facilitates the study of problematic chemicals in such applications as chemical fate modelling, environmental assessments, priority ranking of large lists of chemicals, chemical spill modelling, chemical process design, and experimental design. As the substance is expected to be resistant to hydrolysis based on this considerations the study on hydrolysis is scientifically not necessary and this study is waived according to Annex XI, section 1, to REACH Regulation.
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.
