Acute oral toxicity
In different studies,4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1) has been investigated for acute oral toxicity to a greater or lesser extent. Often are the studies based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats for4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1).The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1).LD50 was estimated to be 28518.73 mg/kg bwmg/kg bw, when male and female Sprague-Dawley rats were exposed with 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)orally.
Also it is further supported by experimental study givenEnviro Control Inc. (Fiber Reactive Dye Toxicological Profile, final report, 1981)on structurally similar read across substanceusing1-Amino-4-(2'-(4'',6''-dichloro-s-triazin-2-yl)amino)phenylamino)9,10-dihydro-9,10-dioxoanthracene-2,4'-disulphonic acid(13324-20-4).Acute oral toxicity study was done in rats using 1-Amino-4-(2'-(4'',6''-dichloro-s-triazin-2-yl)amino)phenylamino)9,10-dihydro-9,10-dioxoanthracene-2,4'-disulphonic acid(13324-20-4).50%mortality was observed at dose 8680mg/kg bw. Hence LD50 was considered to be 8980mg/kg body weight. When rats was treated with1-Amino-4-(2'-(4'',6''-dichloro-s-triazin-2-yl)amino)phenylamino)9,10-dihydro-9,10-dioxoanthracene-2,4'-disulphonic acid(13324-20-4)orally.
Also it is further supported by experimental study givenEnviro Control Inc. (Fiber Reactive Dye Toxicological Profile, final report, 1981)on structurally similar read across substanceusing Reactive Orange 12(12225-84-2).Acute oral toxicity study was done in rats using Reactive Orange 12(12225-84-2).No mortality was observed at dose 5000mg/kg bw. HenceLD50 was considered to be >5000mg/kgbody weight.When rats was treated with Reactive Orange 12(12225-84-2) orally.
Thus, based on the above studies and predictions on4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)and it’s read across substances, it can be concluded that LD50 value is28518.73 mg/kg bw. Thus, comparing this value with the criteria of CLP4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)can be “Not classified” for acute oral toxicity.
Acute dermal toxicity
In different studies,4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)has been investigated for acute dermal toxicity to a greater or lesser extent. Often are the studies based on in vivo experiments and estimated data in rodents, i.e. most commonly in rabbits for4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1) .The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies.
In a prediction done by SSS (2017) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute dermal toxicity was estimated for 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1),LD50 was estimated to be 20758.47 mg/kg bw. When male and femaleNew Zealand Whiterabbits were exposed with 4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)by dermal application.
Also it is further supported by experimental study given byU.S. National Library of Medicine (ChemIDplusA TOXNET Database, 2017).on structurally similar read across substanceusingEthanol, 2.2’-(methylimino)bis- (MDEA) (105 -59 -9) .In dermal toxicity study,4 male New Zealand albino rabbits were treated with Ethanol, 2.2’-(methylimino)bis- (MDEA) in the concentration of 5990 mg/kg bw dermally. No mortality observed in treated rabbits. Therefore, LD50 was considered to be > 5990 mg/kg bw when 4 male New Zealand albino rabbits were treated with Ethanol, 2.2’-(methylimino)bis- (MDEA) (105 -59 -9) by dermal application .
Thus, based on the above studies and predictions on4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)and its read across substances, it can be concluded that LD50 value is 20758.47 mg/kg bw. Thus, comparing this value with the criteria of CLP4-{[4-({3-[(4-amino-6-chloro-1,3,5-triazin-2-yl)amino]-4-sulfophenyl}amino)-6-chloro-1,3,5-triazin-2-yl]amino}-6-[(E)-2-(5-carbamoyl-1-ethyl-2-hydroxy-4-methyl-6-oxo-1,6-dihydropyridin-3-yl)diazen-1-yl]benzene-1,3-disulfonic acid (93941-80-1)can be “Not classified” for acute dermal toxicity
