Abiotic degradation

3-(Triethoxysilyl)propiononitrile hydrolyses rapidly (half-life 6.5 hours at pH 7 and 20°C, measured). A half-life of 0.9 days for reaction with hydroxyl radicals in air has been calculated for 3-(triethoxysilyl)propiononitrile. However, reaction with water vapour, rather than photolysis, may be the primary degradation process in air.

The initial hydrolysis products are expected to be 3-(trihydroxysilyl)propiononitrile and ethanol.

Biotic degradation

A reliable ready biodegradation test has been read-across from an analogous substance which indicates that it is not readily biodegradable, and no significant biodegradation in water of the hydrolysis product, 3-(trihydroxysilyl)propiononitrile, is expected.
