Endpoint:
adsorption / desorption: screening
Data waiving:
study technically not feasible
Justification for data waiving:
the study does not need to be conducted because the substance and its relevant degradation products decompose rapidly
Reason / purpose for cross-reference:
data waiving: supporting information

Description of key information

The study does not need to be conducted because the substance is hydrolytically unstable. However, for PNEC calculation a log Koc of 4.55 was calculated according to Di Toro, 1985 (A particle interaction model reversible organic chemical sorption, Chemosphere 14(10):1503 -1538.


Calculation formula: Adsorption coefficient per organic carbon (Koc): log Koc = 0.00028 + (0.983 x log Kow).

Key value for chemical safety assessment

Koc at 20 °C:
35 610
