Description of key information

Atmospheric photooxidation half-life of 1.1 hours (hydroxyl radicals) has been reported.

Key value for chemical safety assessment

Half-life in air:
1.1 h

Additional information

In Atkinson (1985), measured data from author and other investigators were quality assessed and then used to develop rate constants for different chemicals. Therefore, this value represents a valid rate constant based on all valid studies at the time of publication. The estimated half life is 1.1 hours based on an overall OH rate constant of 119.1993 E-12 cm³ molecule-1 s-1.
