Description of key information

Dissociation constant (substance): Not relevant
Dissociation constant (silanol hydrolysis product): 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 3 -chloropropylsilanetriol and hydrogen chloride. The first dissociation constant of 3 -chloropropylsilanetriol is estimated to be ca. 10, based on read-across from the related substance phenylsilanetriol.
