Additional information

Phototransformation in air

Half-life for reaction with photochemically-produced hydroxyl radicals: estimated to be between 0.645 and 0.967 days.

Hydrolysis

A base-catalysed second-order hydrolysis rate constant of 1.248E-002 L/mol-sec was estimated using a structure estimation method.

This corresponds to half-lives of 17.602 years at pH 7 and 1.76 years at pH 8.

In accordance with REACH Regulation 1907/2006, Annex VIII - Column 2, hydrolysis as a function of pH does not need to be determined as the substance can be regarded as readily biodegradable.
