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 1535 with S9 metabolic activation it was estimated that (3-aminophenyl)uronium chloride 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 1535 with S9 metabolic activation it was estimated that (3-aminophenyl)uronium chloride does not exhibit positive gene mutation effect.
