Description of key information

Estimated rate constant for reaction with atmospheric hydroxyl radicals is 59.75*E -12 cm³/molecule/s.

Key value for chemical safety assessment

Half-life in air:
6.44 h
Degradation rate constant with OH radicals:
0 cm³ molecule-1 d-1

Additional information

Half-life is estimated for the major component in the material derived from second-order rate constant, assuming a tropospheric hydroxyl radical concentration of 500,000 molecules OH/cm3, and 24-hr. The estimated rate constant is 59.75*E -12 cm³/molecule/s and the half-life is 6.44 hrs.
