Description of key information

Dissociation constant (substance): Not relevant
Dissociation constant (read-across substance): ca. 10

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 to form (2,4,4,trimethylpentyl)silanetriol and hydrogen chloride. The first dissociation constant of the silanetriol is estimated to be ca. 10, based on read-across from the related substance phenylsilanetriol.
