Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Due to the UVCB nature of the substance the test is not considered techncially possible.
Key value for chemical safety assessment
Additional information
The nature of the substance makes determination of dissociation constant technically challenging. MK92K is considered to be a UVCB substance comprising multiple components, of similar chemical functionality, in varying proportions. Whilst MK92K possess functionality that could be anticipated to dissociate under environmental conditions, it would not be expected to behave in a traditional manner and yield a single dissociation constant. As the number of components is significant, and variable it would also present a significant technical challenge to isolate these in order to determine the individualdissociation constants.
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.
