Endpoint summary

Description of key information

Acute oral toxicity:

Data available for the structurally and functionally similar read across chemicals has been reviewed to determine the acute oral toxicity of the test chemical Trisodium hydrogen [2-[[α-[[3-[[4-chloro-6-[ethyl[3-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-2-hydroxy-5-sulphophenyl]azo]benzyl]azo]-4-sulphobenzoato(6-)]cuprate(4-) (CAS no.: 84057-71-6). The studies are as mentioned below:

WoE 2:

Acute oral toxicity study was conducted in rats using test material at the concentration of 7460 mg/kg bw. 50% mortality was observed at dose 7460 mg/kg bw. Hence, LD50 value was considered to be 7460 mg/kg bw, when rats were treated with test chemical via oral route.

WoE 3:

Acute oral toxicity study was conducted in rats using test material at the dose concentration of 8980 mg/kg bw. 50% mortality was observed at dose 8980 mg/kg bw. Hence, LD50 value was considered to be 8980 mg/kg bw, when rats were treated with test chemical via oral route.

Thus, based on the above summarised studies, Trisodium hydrogen [2-[[α-[[3-[[4-chloro-6-[ethyl[3-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-2-hydroxy-5-sulphophenyl]azo]benzyl]azo]-4-sulphobenzoato(6-)]cuprate(4-) (CAS no.: 84057-71-6) and it’s structurally and functionally similar read across substances, it can be concluded that LD50 value is >2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Trisodium hydrogen [2-[[α-[[3-[[4-chloro-6-[ethyl[3-[[2-(sulphooxy)ethyl]sulphonyl]phenyl]amino]-1,3,5-triazin-2-yl]amino]-2-hydroxy-5-sulphophenyl]azo]benzyl]azo]-4-sulphobenzoato(6-)]cuprate(4-) (CAS no.: 84057-71-6) cannot be classified for acute oral toxicity. Hence, Trisodium hydrogen [2-[[α-[[3-[[4-chloro-6-[ethyl[3-[[2-(sulphooxy)ethyl]sulphonyl] phenyl]amino]-1,3,5-triazin-2-yl]amino]-2-hydroxy-5-sulphophenyl]azo]benzyl]azo]-4-sulphobenzoato(6-)]cuprate(4-) is not toxic for acute oral toxicity.
