Description of key information

The hydrolysis of 1,3-bis(3-methyl-2,5-dioxo-1H-pyrrolinylmethyl)benzene was determined

at pH 4 and yielded half lifes of 1841 h at 25 °C, 676.7 h at 50 °C , 78.1 h at 80 °C and 41.9 h at 90 °C. The determination at pH 7 gave a half-life of 68.5 h at 25 °C and 6.1 h at 50 °C; and at pH 9 <2.4 h at 50 °C. The degradation products were not reported.

Key value for chemical safety assessment

Half-life for hydrolysis:
68.5 h
at the temperature of:
25 °C
