Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- JUSTIFICATION FOR DATA WAIVING
[Specific explanation in addition to field 'Justification for data waiving']
Determining the dissociation constant of the substance is technically not feasible as no method will work effectively for the following reasons:
1) The substance does not contain any chromophores so a spectrophotometric method will not be feasible.
2) The conductivity method is not feasible due to the low water solubility of the substance.
3) The potentiometric titration method will not be possible due to the overlapping pKa’s and the low water solubility.
4) The low water solubility will make it extremely difficult to quantify the substances pKa value even if a method was available.

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.
