Description of key information
Prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for N-phenyl-4-[[4-(phenylamino)phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride ( 2152-64-9).The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without S9 metabolic activation system. N-phenyl-4-[[4-(phenylamino) phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride was predicted to not induce gene mutation in Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 in the presence and absence of S9 metabolic activation system and hence, according to the prediction made, it is not likely to classify as a gene mutant in vitro. Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.

Additional information
Prediction model based estimation and data from read across chemical have been reviewed to determine the mutagenic nature of N-phenyl-4-[[4-(phenylamino) phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride ( 2152-64-9). The studies are as mentioned below
Based on the prediction done using the OECD QSAR toolbox version 3.3 with log kow as the primary descriptor and considering the five closest read across substances, gene mutation was predicted for N-phenyl-4-[[4-(phenylamino)phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride ( 2152-64-9).The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with and without S9 metabolic activation system. N-phenyl-4-[[4-(phenylamino) phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride was predicted to not induce gene mutation in Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 in the presence and absence of S9 metabolic activation system and hence, according to the prediction made, it is not likely to classify as a gene mutant in vitro. Based on the predicted result it can be concluded that the substance is considered to not toxic as per the criteria mentioned in CLP regulation.
Gene mutation toxicity was predicted for N-phenyl-4-[[4-(phenylamino)phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride ( 2152-64-9)using the battery approach from Danish QSAR database (2017). The study assumed the use of Salmonella typhimurium bacteria in the Ames test. The end point for gene mutation has been modeled in the Danish QSAR using the three software systems Leadscope, CASE Ultra and SciQSAR. Based on predictions from these three systems, a fourth and overall battery prediction is made. The battery prediction is made using the so called Battery algorithm. With the battery approach it is in many cases possible to reduce “noise” from the individual model estimates and thereby improve accuracy and/or broaden the applicability domain.
Gene mutation toxicity study as predicted by N-phenyl-4-[[4-(phenylamino)phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride is negative and hence the chemical is predicted to not classify as a gene mutant in vitro.
In a study for structurally and functionally similar read across chemical, Gene mutation toxicity study was conducted by William Au et al.( Mutation Research,1979)to determine the mutagenic nature of Gentian violet (548-62-9). The read across substances share high similarity in structure and log kow .Therefore, it is acceptable to derive information on mutation from the analogue substance. Ames mutagenicity assay was performed to study the mutagenic potential of gentian violet both in the presence and absence of metabolic activator S9 mix. The study was performed using Salmonella typhimurium TA98, TA100, TA1535, TA1537 at dose levels of 0, 0.1, 1.0, 10., 25.0 or 50.0 µg/plate. The test chemical was dissolved in DMSO and used for the study. Plates were incubated in dark at 37°C for 48 hrs before counting his+ revertant colonies and each dose point was determined from at least two plates. Gentian violet did not induce gene mutagenicity in the Salmonella typhimurium TA98, TA100, TA1537 and TA1535 strains in the presence and absence of S9 mix and hence it is not likely to classify as a gene mutant in vitro.
In a study for structurally and functionally similar read across chemical, Gene mutation toxicity study was performed by Errol Zeiger et.al. (Environmental and Molecular Mutagenesis ,1992) to determine the mutagenic nature of n- Nonane(111-84-2). The read across substances share high similarity in structure and log kow .Therefore, it is acceptable to derive information on mutation from the analogue substance. Gene mutation toxicity study was performed to determine the mutagenic nature of n- Nonane. The study was performed usingSalmonella typhimurium strainsTA97, TA98, TA100, TA1535 and TA1537 in the presence and absence of S9 metabolic activation system. The chemical was dissolved in water as solvent and used at dose levels 0, 100, 333, 1000, 3333 or 10000 µg/plate by the preincubation method. The doses were selected on the basis of preliminary dose range finding study and concurrent solvent and positive controls were included in the study. n- Nonanedid not induce gene mutation in Salmonella typhimuriumTA97, TA98, TA100, TA1535 and TA1537 in the presence and absence of S9 metabolic activation system and hence is not likely to classify as a gene mutant in vitro.
Based on the data available for the target chemical and its read across substance and applying weight of evidence N-phenyl-4-[[4-(phenylamino) phenyl][4-(phenylimino)cyclohexa-2,5-dien-1-ylidene]methyl]aniline monohydrochloride ( 2152-64-9) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro.
Justification for classification or non-classification
Thus based on above annotation and CLP criteria for the target chemical . N-phenyl-4-[[4-(phenylamino) phenyl][4-(phenylimino) cyclohexa-2,5-dien-1 -ylidene]methyl] aniline monohydrochloride ( 2152-64-9) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro.
