Description of key information
Half-life for reaction with photochemically-produced hydroxyl radicals: estimated to be 13.251 hours
Key value for chemical safety assessment
- Half-life in air:
- 45.3 h
Additional information
Phototransformation in air was assessed from read across approach data available for the structural analogue 4-MHHPA as similar chemical and environmental fate properties were assumed. Stability of the substance in the atmosphere was calculated using the computer program AOPWIN (v 1.92). It is predicted that the substance will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals. The half-life for this reaction in air is estimated to be approximately 45 hours
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
