Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Conclusions:
Overall OH rate constant estimated by Epi-Suite at 12.24e-12 cm3/(mole*s). Using equation R.16-12 (ECHA Guidance on safety assessment, R16) this corresponds to a half-life in air of 1.3 d
Executive summary:

Overall OH rate constant estimated by Epi-Suite at 12.24e-12 cm3/(mole*s). Using equation R.16-12 (ECHA Guidance on safety assessment, R16) this corresponds to a half-life in air of 1.3 d

Description of key information

The overall OH rate constant was estimated by EpiSuite at 12.21e-12 cm3/(mole*s). This corresponds to a half-life in air of 1.3 d according to equation R.16-12 in the ECHA Guidance on safety assessment, R16. 

Key value for chemical safety assessment

Half-life in air:
1.3 d

Additional information

The overall OH rate constant was estimated by EpiSuite at 12.21e-12 cm3/(mole*s). This corresponds to a half-life in air of 1.3 d according to equation R.16-12 in the ECHA Guidance on safety assessment, R16.
