Rationale for reliability incl. deficiencies:
other: Meets generally accepted scientific standards, well document and acceptable for assessment
Justification for type of information:
QSAR prediction: migrated from IUCLID 5.6
Principles of method if other than guideline:
AOPWIN v1.92 and v1.91 accessed via Epiweb v 4.10
Estimation method (if used):
PHOTOCHEMICAL REACTION WITH OH RADICALS
- Computer programme: AOPWIN v1.92 and v1.91 accessed via Epiweb v 4.10

Physical property inputs:
- Log Kow (octanol-water): 4.60
- Boiling Point (deg C): 235.00
- Melting Point (deg C): -20.00
- Vapour Pressure (mm Hg): 0.098
- Water solubility (mg/L): 7.81

Half-lives (hr), (based upon Biowin (ultimate) and Aopwin):

Air: 5.55

Conclusions:
The phototransformation half-life of the test item in air was calculated as 5.545 hours using EPIsuite-AOPWIN.
