Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information

KDDC is susceptible to indirect photodegradation in air (half-life = 4.6 h)

Key value for chemical safety assessment

Additional information

The dissipation half-life of KDDC (CAS No. 128-03-0) in air was estimated using the AOPWIN subroutine from the EPISuite™ computer program (US EPA), resulting in a half-life of 4.6 hours. Thus, KDDC is susceptible to indirect photodegradation in air. Due to the short chemical lifetime of this substance in air it is not to be expected that it will accumulate in air or be transported in the gaseous phase over long distances. Hence, air will not be an environmental compartment of concern.
