Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
pKa of ammonia: 9.25 at 25 °C
pKa of alkyl sulfate: 0.91 at 20 °C
Key value for chemical safety assessment
Additional information
Due to the dissociation constants of the corresponding alkyl sulfate (pKa < 2) and the ammonia (pKa = 9.25), it can be assumed that the substance is existent as a salt and thus completely dissociated in the range of pH 5 - 9.
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.
