Acute oral toxicity study was done in 5 male and 5 female Wistar (SPF cpB)rats using test material Sodium 4-chloro-3-nitrobenzenesulphonate(17691-19-9) following 14 days of observation period.Rats were 14 weeks old.Initial weight of male animals was 161 g and the female rats had an average initial weight of 160 g. The rats were conventionally kept in Makrolonkaefigen type III on dust-free wood granules at a room temperature of 22 +/- 1.5 degrees Celsius and 2 hours of light / dark rhythm (artificial lighting from 7 am to 7 pm CET) and a relative humidity of approx. 60 +/- 5% in groups of 5 each animals.The feed,Altromin R 1324 was given ad libitum. Water was provided ad libitum for approximately 16 hours and before until about 4 hours after application.Water was used as vehicle.The substance was formulated in water using a rigid metal stomach probe in koaslantem. Application volume (20 ml / kg body weight) to each 5

males and 5 females were given once. After 1 week and at the end of the 14 days animals were weighed individually.No mortality was observed at dose 5000 mg/kg bw.No poisoning symptoms were observed in animals.The section of some animals killed at the end of the experiment showed no macroscopic findings.Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated withSodium 4-chloro-3-nitrobenzenesulphonate(17691-19-9) orally.

Additional information

Acute Oral Toxicity:

In different studies, Sodium 4-chloro-3-nitrobenzenesulphonate (17691-19-9)has been investigated for acute oral toxicity to a greater or lesser extent. Often the studies are based on in vivo experiments and estimated data in rodents, i.e. most commonly in rats for Sodium 4-chloro-3-nitrobenzenesulphonate (17691-19-9).

In an experimental study conducted by Sustainability Support Services (Europe) AB (Institute of Toxicology,wuppertal,1982-07-29,Report no. T8014021) for the target substance Sodium 4-chloro-3-nitrobenzenesulphonate (17691-19-9). Acute oral toxicity study was done in 5 male and 5 female Wistar (SPF cpB)rats using test material Sodium 4-chloro-3-nitrobenzenesulphonate(17691-19-9) following 14 days of observation period.Rats were 14 weeks old.Initial weight of male animals was 161 g and the female rats had an average initial weight of 160 g. The rats were conventionally kept in Makrolonkaefigen type III on dust-free wood granules at a room temperature of 22 +/- 1.5 degrees Celsius and 2 hours of light / dark rhythm (artificial lighting from 7 am to 7 pm CET) and a relative humidity of approx. 60 +/- 5% in groups of 5 each animals.The feed,Altromin R 1324 was given ad libitum. Water was provided ad libitum for approximately 16 hours and before until about 4 hours after application.Water was used as vehicle.The substance was formulated in water using a rigid metal stomach probe in koaslantem. Application volume (20 ml / kg body weight) to each 5 males and 5 females were given once. After 1 week and at the end of the 14 days animals were weighed individually.No mortality was observed at dose 5000 mg/kg bw.No poisoning symptoms were observed in animals.The section of some animals killed at the end of the experiment showed no macroscopic findings.Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated with Sodium 4-chloro-3-nitrobenzenesulphonate(17691-19-9) orally.

In another experimental study conducted by European Chemicals Bureau (ECB)( IUCLID DATASET, European Chemicals Bureau (ECB), 18–FEB–2000) for the target substance Sodium 4-Chloro-3-Nitrobenzenesulphonate (17691-19-9). Acute oral toxicity study was done in rats using test material Sodium 4-Chloro-3-Nitrobenzenesulphonate (17691-19-9).No mortality was observed at dose 5000 mg/kg bw. Hence,LD50 value was considered to be >5000 mg/kg bw,when rats were treated with Sodium 4-Chloro-3-Nitrobenzenesulphonate (17691-19-9)orally.

 Also these results are further supported by the experimental study conducted by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) and IFA GESTIS (GESTIS SUBSTANCE Database ,2017) for the structurally similar read across substance Sodium 3-nitrobenzenesulphonate (127-68-4). Acute oral toxicity study was done in rats using test material Sodium 3-nitrobenzenesulphonate(127-68-4).50% mortality was observed at dose 11000 mg/kg bw. Hence,LD50 value was considered to be 11000 mg/kg bw,when rats were treated with Sodium 3-nitrobenzenesulphonate (127-68-4)orally.

Thus, based on the above studies and predictions on Sodium 4-chloro-3-nitrobenzenesulphonate (17691-19-9) and its structurally similar read across substances, it can be concluded that LD50 value was >5000 mg/kg bw.Thus,comparing this value with the criteria of CLPregulation,Sodium 4-chloro-3-nitrobenzenesulphonate (17691-19-9) can be “Not classified” for Acute Oral Toxicity.

Justification for classification or non-classification

Thus, comparing this value with the criteria of CLPregulation,Sodium 4-chloro-3-nitrobenzenesulphonate(17691-19-9) can be “Not classified” for Acute Oral Toxicity.
