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 Disodium2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate. 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. Disodium2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate 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

Prediction model based estimation and data from read across chemical have been reviewed to determine the muategnic nature of Disodium 2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate(84000 -63 -5). 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 Disodium2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate. 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. Disodium2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate 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 Disodium 2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate 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 Danish QSAR for Disodium 2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy)ethanesulfonyl]phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonateis 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 performed by H. E. Seifried et al. (Chem. Res. Toxicol., 2006 () to determine the mutagenic nature of C.I Briliant black BN (RA CAS no2519-30-4; IUPAC name: tetrasodium 4-acetamido-5-hydroxy-6-({7-sulfonato-4-[(4-sulfonatophenyl)diazenyl]-1-naphthyl}diazenyl)naphthalene-1,7-disulfonate ). 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. The mutagenic potency of C.I Brilliant black BN (2519-30-4) was tested by the plate incorporation method using Salmonella typhimuriumstrainTA98, TA100, TA1535, TA1537, and TA1538. When the test bacterial strain is exposed with the test chemical for 48hrs, no mutagenic response was seen in any of the strains of Salmonella typhimurium (with and without metabolic activation system). Therefore C.I Brilliant black BN (2519-30-4) was not likely to be classified as a gene mutant in vitro.
In a study for structurally and functionally similar read across chemical, Gene mutation toxicity study was performed by Fred Joachimet al. (Mutation Research, 1985) to determine the mutagenic nature of Food black 2 (2118-39-0); IUPAC name: tetrasodium (3E)-6-amino-4-oxo-3-(2-{7-sulfinato-4-[(E)-2-(4-sulfonatophenyl)diazen-1-yl]naphthalen-1-yl}hydrazin-1-ylidene)-3,4-dihydronaphthalene-2,7-disulfonate . 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. Genetic toxicity in Vitro was conducted for Food black 2 (2118-39-0) by Salmonella/microsome assay.Food black 2was tested by the Standard plate method in Salmonella typhimuriumstrainTA98, TA100, TA1535, TA1537, and TA1538.When the test bacterial strain is exposed with the test material at the concentration of0-5 mg/Plate, no mutagenic response was seen in any of the strains of Salmonella typhimurium (with and without metabolic activation system). A significant mutagenic response was observed in positive control. Therefore Food black 2 was not likely to be classified 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 Disodium 2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1-yl}-4-{[4-chloro-6-({3-[2-(sulfonatooxy) ethanesulfonyl] phenyl}amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate (CAS no84000-63-5) 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 the above annotation and CLP criteria Disodium 2-{2-[(3Z)-5-carbamoyl-1-ethyl-4-methyl-2,6-dioxo-1 ,2,3,6-tetrahydropyridin-3-ylidene]hydrazin-1 -yl} -4-{[4-chloro-6-({3-[2-(sulfonatooxy) ethanesulfonyl]phenyl} amino)-1,3,5-triazin-2-yl]amino}benzene-1-sulfonate (CAS no84000-63-5) does not exhibit gene mutation in vitro.
