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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
It can be determined that the substance would always be ionised at environmentally relevant pH’s.
Key value for chemical safety assessment
Additional information
Dissociation Constants in Water.
No determination was possible according to Method 112 of the OECD Guidelines for Testing of Chemicals, 12 May 1981, due to the presence of overlapping dissociation constants. Therefore, the dissociation constants were estimated using Advanced Chemistry Development I-Lab Web Service (ACD I-Lab 2.0). The estimated pKavalues are presented in the following table:
Functional Group |
Dissociation Constants |
Monoesters: -P-OH (two) |
1.95, 1.96±0.10 |
Diesters: -P-OH |
1.50, 1.51±0.50 |
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.
