Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Degradation in air: OTNE is photodegradable in air. The rate constant for the gas phase reaction of OH radicals was estimated at 9.85*10-11cm3molecule-1s-1. Assuming a daylight period of 12 h and 2.0*106OH cm-3, the estimated atmospheric half-life is 1.4 hours. These data suggest that the atmospheric life time of OTNE is sufficiently short that it will not undergo long-range transport to any significant extent.

Degradation in water: A hydrolysis test for this substance is waived based on the absence of chemical groups that can undergo hydrolysis and on the rapid biodegradation of OTNE under natural conditions in river water.
