Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Rate constant (for indirect photolysis):  0.00000000017 cm³/(molecule*sec) Degradation in % (for indirect photolysis): = 50  after 2.3 hour(s)

Key value for chemical safety assessment

Half-life in air:
2.3 h
Degradation rate constant with OH radicals:
0 m³ molecule-1 s-1

Additional information

The Rate constant for indirect photolysis has been calculated by using the AOPWIN program (version 1.91) and is estimated to be 0.00000000017 cm³/(molecule*sec). The half-life in air of the test substance is estimated to be 2.3 hours.
