Description of key information
The calculated half-life of o-toluidine by photodegradation in air was 2.915 hours with an Overall OH rate constant of 132.0953E-12 cm³/molecule-sec.
Key value for chemical safety assessment
- Half-life in air:
- 2.915 h
- Degradation rate constant with OH radicals:
- 0 cm³ molecule-1 s-1
Additional information
The indirect photodegradation in air was calculated with the Estimation Program Interface EPI-Suite version 4.11. The estimated half-life of the substance was 2.915 hours with an Overall OH rate constant of 132.0953E-12 cm³/molecule-sec considering a daily (24h) mean OH-radical concentration of 500 000 radicals per cm3.
The estimation rules applied for the substance appears appropriate.
The predicted result for o-toluidine can be considered reliable yielding a useful result for further assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
