Additional information

Diketon (ZK 233744) did not show a mutagenic potential in a bacterial reverse mutation assay (S. typhimurim strains TA 1535, TA 100, TA 1537, TA 1538 and TA98) when tested up to the maximum recommended dose level of 5 mg/plate in the absence and presence of extrinsic metabolic activation (liver S9 mix from Aroclor 1254 -treated rats). No Growth inhibition and no precipitates in the agar were observed up to 5.0 mg/plate.
