The purpose of this study was to determine the mutagenicity of the test substance Normal-Heptane. A reverse mutation assay was done using S. typhimurium strains TA 1535, TA 1537, TA 1538, TA 98 and TA 100, and E. coli strains WP2 and WP2 uvr A. The strains were exposed to concentrations of 0, 3.91, 7.81, 15.6, 31.3, 62.5, 125, and 250 ug/mL for 48 -72 hrs both with and without metabolic activation. The number of revertant colonies was then counted.
No significant increases in the ratio of mutations over controls was seen. The test substance is not mutagenic in either the presence or absence of metabolic activation. - Executive summary:
This data is being read across from the source study that tested Heptane based on analogue read across.
The purpose of this study was to determine the mutagenicity of the test substance Normal-Heptane. A reverse mutation assay was done using S. typhimurium strains TA 1535, TA 1537, TA 1538, TA 98 and TA 100, and E. coli strains WP2 and WP2 uvr A. The strains were exposed to concentrations of 0, 3.91, 7.81, 15.6, 31.3, 62.5, 125, and 250 ug/mL for 48 -72 hrs both with and without metabolic activation. The number of revertant colonies was then counted.
No significant increases in the ratio of mutations over controls was seen. The test substance is not mutagenic in either the presence or absence of metabolic activation.
The addition of heptane at amounts up to 250 µg per mL to cultures of Escherichia coli WP2 and WP2 uvr A, Salmonella typhimurium TA 1535, TA 1537, TA 1538, TA 98, and TA 100 did not lead to an increase in the reverse gene mutation frequency in any of these strains, either in the presence or in the absence of rat liver S9 fraction.

Applicant's summary and conclusion
- Conclusions:
- Interpretation of results (migrated information):
negative
The purpose of this study was to determine the mutagenicity of the test substance Normal-Heptane. A reverse mutation assay was done using S. typhimurium strains TA 1535, TA 1537, TA 1538, TA 98 and TA 100, and E. coli strains WP2 and WP2 uvr A. The strains were exposed to concentrations of 0, 3.91, 7.81, 15.6, 31.3, 62.5, 125, and 250 ug/mL for 48 -72 hrs both with and without metabolic activation. The number of revertant colonies was then counted.
No significant increases in the ratio of mutations over controls was seen. The test substance is not mutagenic in either the presence or absence of metabolic activation. - Executive summary:
