Description of key information

Additional information

Stability of analogs of the substance in the atmosphere was calculated using the software AOPWIN (v 1.92) as the substance itself was recognised by the software. The analogs examined were predicted to be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air ranged from 0.5 hours to 4.3 hours with an average of approximately 2.2 hours.

The rate of hydrolysis of analogs of the substance in aqueous media has been estimated using QSAR methods, the substance itself not being recognised by the software used. Half-lives of 1 to 1.7 years (average 1.35 years) at pH7 and 36.47 to 62.35 days (average 50 days) at pH 8 are predicted.
