Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Phototransformation in air
Administrative data
Link to relevant study record(s)
- Endpoint:
- phototransformation in air
- Type of information:
- (Q)SAR
- Adequacy of study:
- key study
- Study period:
- Not applicable
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- results derived from a valid (Q)SAR model and falling into its applicability domain, with adequate and reliable documentation / justification
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- The gas-phase oxidation rate and half-life was calculated using the atmospheric oxidation program AOPwin, contained in the EPA's estimation program interface suite.
- GLP compliance:
- no
- Key result
- DT50:
- 2.155 h
- Test condition:
- Based upon a hydroxyl radical concentration of 1.5 x 10^6 molecules/cubic cm (12 hour day), a half-life of 2.155 hours was calculated.
- Validity criteria fulfilled:
- yes
- Conclusions:
- Under the conditions of the test, the gas-phase oxidation rate of the test material in the troposphere was calculated to be 59.5637 x 10E-12 cubic cm/molecule-sec. A half-life of 2.155 hours was calculated.
- Executive summary:
Under the conditions of the test, the gas-phase oxidation rate of the test material in the troposphere was calculated to be 59.5637 x 10-12 cubic cm/molecule-sec. A half-life of 2.155 hours was calculated.
Reference
The gas-phase oxidation rate of the test substance in the troposphere was predicted to be 59.5637 x 10-12 cm3/molecule-sec. Based upon a hydroxyl radical concentration of 1.5 x 106 molecules/cubic cm (12 hour day), a half-life of 2.155 hours was calculated.
Description of key information
Half-life of 2.155 hours; estimated using AOPWIN; Schocken (2002)
Key value for chemical safety assessment
- Half-life in air:
- 2.155 h
Additional information
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.
