Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Executive summary:

Kloepffer 1990


Using the Atkinson calculation method and assuming hydroxyl radicals as sensitizer for indirect photolysis (ensitiser concentration: 500000 molecule/cm³), the following results for 3,4-dichlorophenyl isocyanate were obtained:


Rate constant (for indirect photolysis): 0.00000000000075 cm³/(molecule*sec)
Degradation in % (for indirect photolysis): ca. 50 after 21 day(s)
