Description of key information

The QSAR calculated rate constant for the OH sensitized photodegradation of dodecanedioic acid is approximately 1.41E-11 cm3/(molecule * s) (AopWin Computer Program, Vers. 1.92, integrated in U.S. EPA's EPI  program Vers. 4.1). At 500,000 OH radicals / cm3, this corresponds to a half-life of 27.4 hours.

Key value for chemical safety assessment

Half-life in air:
27.4 h
Degradation rate constant with OH radicals:
1.41 cm³ molecule-1 s-1
