Description of key information

Based on EPI prediction Level III Fugacity Model (EPI suite, 2016), the estimated half life period of 3 -(1H-benzimidazol-2 -yl)-7 -(diethylamino)-2- benzopyrone(CAS no. 27425-55-4)in soil was obtained to be 75 days (1800 hrs). Based on this half life value of 3 -(1H-benzimidazol-2 -yl)-7 -(diethylamino)-2-benzopyrone, it is concluded that the chemical is not persistent in the soil environment.

Key value for chemical safety assessment

Half-life in soil:
75 d
at the temperature of:
25 °C
