Description of key information

Biodegradation in water (screening tests): 0% in 28 days (OECD 310)

Key value for chemical safety assessment

Additional information

A ready biodegradation study is available. Trichloro(phenyl)silane hydrolyses very rapidly to phenylsilanetriol and was used in the test as parent substance on the understanding that it would hydrolyse rapidly to produce the test substance. This is selected as the key study.
