Description of key information

In a study conducted according to OECD guideline 111 it could be demonstrated that TDI-Urone hydrolyses relatively slowly. Normally the longest hydrolysis half-life would be selected for the assessment of the substance which is t1/2 = 257 d at pH4 at the standard test temperature for hydrolysis of 25 °C. Therefore, TDI-urone can be considered to be relatively stable against abiotic degradation.
