Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Examination of Ethyl 2-Methylpentanoate for Mutagenic Activity in the Ames Test: Ethyl 2-methylpentanoate did not show mutagenic activity in Salmonella typhimurium TA 1535, TA 1537, TA 1538, TA 98 and TA 100, either in the absence or in the presence of the S-9 mix, under the conditions employed in this evaluation.

In vitro mammalian cell gene forward mutation test at the hgprt locus of the Chinese hamster ovary (CHO)-K1 cell line using Ethyl 2-methylvalerate (ethyl 2-methypentanoate): From these results, it is concluded that ethyl 2-methylvalerate (ethyl 2-methylpentanoate) does not have potential to induce gene mutations at the hgprt locus of CHO-K1 cells both in the absence and presence of metabolic activation under the present experimental conditions.

In vitro mammalian chromosome aberration test of ethyl 2-methylvalerate (Ethyl 2-methylpentanoate) in human peripheral blood lymphocytes: From the results of this study, it is concluded that ethyl 2-methylvalerate (ethyl 2-methypentanoate) did not show any potential to induce chromosomal aberrations, both in the absence and presence (2 and 4% v/v S9) of metabolic activation under the present experimental conditions.


Endpoint Conclusion: No adverse effect observed (negative)
