Description of key information
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 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate. The study assumed the use of Salmonella typhimurium strains TA 1535, TA 1537, TA 98, TA 100 and TA 102 with S9 metabolic activation system. 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate 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 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 be not toxic as per the criteria mentioned in CLP regulation.

Additional information
Gene mutation in vitro:
Prediction model based estimation and data from read across chemicals have been reviewed to determine the mutagenc nature of
4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate. The studies are as summrized 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 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate. 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. 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate 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.
In a study for read across chemical by Lavoei et al (Mutation reaserch, 1979), 4-Aminophenyl sulfone (RA CAS no 80 -08 -0) was studied for its ability to induce mutations in strains of Salmonella typhimurium. The test compound was dissolved in DMSO and was tested at concentration of 0, 25, 50, 100, 250 or 500 µg/plate using Salmonella typhimurium TA100 and TA98 in the presence and absence of S9 metabolic activation system. 4-Aminophenyl sulfone is not mutagenic to the Salmonella typhimurium TA100 and TA98 in the presence and absence of S9 metabolic activation system.
Zeiger et al (Environmental Mutagenesis, 1986) performed gene mutation toxicity study for read across Sulfamethazine (RA CAS no 57 -68 -1) to evaluate its mutagenic nature. The study was performed as per the preincubation protocol using Salmonella typhimurium strain TA100, TA1535, TA1537, TA98 both in the presence and absence of S9 metabolic activation system at doses of 0, 3, 10, 33, 100, 333 or 1000µg/plate. DMSO was used as the vehicle. The plates were incubated for 48 hrs after 20 mins preincubation before the evaluation of the revertant colonies could be made. Sulfamethazine did not induce mutation in the Salmonella typhimurium strain TA100, TA1535, TA1537, TA98 both in the presence and absence of S9 metabolic activation system and hence the chemical is not likely to classify as a gene mutant in vitro.
Based on the data available for the target chemical and its read across, 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro as per the criteria mentioned in CLP regulation.
Justification for classification or non-classification
Based on the data available for the target chemical and its read across, 4-amino-N-(4-aminophenyl)-N-(4-methylenecyclohexa-2,5-dien-1-ylidene)anilinium acetate (CAS no 6035 -94 -5) does not exhibit gene mutation in vitro. Hence the test chemical is not likely to classify as a gene mutant in vitro as per the criteria mentioned in CLP regulation.
