Key value for chemical safety assessment

Additional information

The substance was shown to be clastogenic in chromosome aberration assays but was not mutagenic in the AMES assay. An in vivo rat micronucleus test showed no effect after IV dosing but was weakly positive following oral dosing. An additional in vivo rat micronucleus and comet assay was negative following both IV and oral dosing.
