Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The substance can be regarded as a hydrocarbon with an acetal functional group (that is not typical acid / base moiety). It comports ionisable oxygens, but a SPARC calculation reveals that the pKa is > 10 (between 13.98 and 14.87). So following the "Guidance on information requirements and Chemical Safety Assessment Chapter R.7.a" point R.7.1.17 we can say that the substance will tend not to dissociate in water under normal environmental conditions.

Therefore, a dissociation constant study is not required.
