Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information):
negative with metabolic activation

Based on the prediction for in-vitro bacterial reverse mutation assay test on Salmonella typhimurium strain TA 100 with S9 metabolic activation it was estimated that ethyl 4,4,4-trifluoroacetoacetate does not exhibit positive gene mutation effect.
Executive summary:

Based on the prediction for in-vitro bacterial reverse mutation assay test on Salmonella typhimurium strain TA 100 with S9 metabolic activation it was estimated that ethyl 4,4,4-trifluoroacetoacetate does not exhibit positive gene mutation effect.
