Description of key information

Dissociation constant (dimethylsilanediol): ca. 11.9

Key value for chemical safety assessment

Additional information

The requirement to test the substance for dissociation constant is waived because in contact with water the substance rapidly hydrolyses. The eventually hydrolysis product is dimethylsilanediol. The dissociation of this substance is given in secondary literature as 11.9; this is consistent with values for related substances.
