Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

There are no measured data available for the dissociation constant of 3,3’-Methylen-bis-[5-methyl-oxazolidine]. Due to hydrolysis determination of single pKa values are not possible.

Key value for chemical safety assessment

Additional information

The substance is handled as aqueous solution. The pH value of a 0.2% aqueous solutions is 9.57 (see 4.20) indicating basic properties of nitrogen containing constituents. However, the substance hydrolyses in aqueous solution releasing formaldehyde (equilibrium). 3,3’- Methylene-bis [5-methyl-oxazolidine], can not be isolated and therefore determinations of the single pKa values are not possible.
