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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Any other information on results incl. tables
No experimental values for the temperature and pH are available. The standard programm usualy calculates these values at 25°C and for the uncharged molecules. The pH value for these substance is around 2,5. For these reasons it has been assumed, because the experimental and calculated values are quite close, it can be inferred that the molecule is nearly uncharged and therefore the experimental value can regarded as sufficient valid.
Applicant's summary and conclusion
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.
