Dissipation half-life parent compound = 106.97 hours

Key value for chemical safety assessment

Additional information

The photolysis of sodium 2,4-dichlorophenoxyacetate (CAS No. 2702-72-9) in air was calculated using the AOPWIN subroutine from EPISuite™ computer program (US EPA). The resulting dissipation half-life was determined to be 106.97 hours.
