Trimethoxyphenylsilane is expected to
hydrolyse rapidly (DT50 = 0.4 hours at 25°C) and the silanol hydrolysis
product is not readily biodegradable. Trimethoxyphenylsilane is not
classified for the environment in the EU according to Regulation (EC) No
1272/2008 because good quality data for the analogue
substance, trichloro(phenyl)silane (98-13-5), have been read across.
Both the target and source substances share the same silanol hydrolysis
product, phenylsilanetriol. The other, alcohol hydrolysis products are
methanol (target) and hydrochloric acid (source), respectively. Methanol
and hydrochloric acid are not expected
to be hazardous at concentrations relevant to aquatic toxicity studies.
Experimental results indicate that the silanol hydrolysis product is not
hazardous up to a concentration of 100 mg/L (nominal).
