Description of key information
Read across from Sarolaner API:
The test article was tested in the Bacterial Reverse Mutation Assay using Salmonella typhimurium tester strains TA98, TA100, TA1535 and TA1537 and Escherichia coli tester strain WP2 uvrA (pKM101) in the presence and absence of Aroclor-induced rat liver S9 in accordance with OECD 471. The assay was performed in 2 phases, using the plate incorporation method.
Under the conditions of this study, test article was concluded to be negative in the Bacterial Reverse Mutation Assay.

Additional information
Justification for classification or non-classification
Ames test, Read across from Sarolaner API, OECD 471, negative
Therefore in accordance with Regulation (EC) No. 1272/2008 Table 3.5.1, the test substance should not be classified as germ cell mutagens.
