Description of key information

Removal from the atmosphere by reaction in sunlight is predicted to be rapid:
- reaction with atmospheric OH radicals: rate constant 37.2817 E-12 cc/molecule-sec, half-life 3.449 hours
- reaction with atmospheric ozone: rate constant 1.2 E-17 cc/molecule-sec, half-life 22.92 hours.

Key value for chemical safety assessment

Half-life in air:
3.449 h

Additional information

Phototransformation rates and half-lives have been estimated using QSAR (EPISuite v 4.0).
