Description of key information
Reproductive toxicity
The reproductive toxicity of 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2)was estimated by SSS (2017) using OECD QSAR toolbox v3.3with log kow as the primary descriptor and NOAEL was estimated to be 615.55mg/kg bw.When male and female Sprague-Dawley rats were exposed with 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) orally.Thus, based on the above predictions and experimental study on 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) and its structurally similar read across substance No Observed Adverse Effect Level (NOAEL) was considered to be 615.55 mg/kg bw . Thus, comparing this value with the criteria of CLP regulation 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) cannot be classified as reproductive toxicant.

Additional information
Reproductive toxicity
In different studies 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2)has been investigated for reproductive 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 for 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2). The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies performed on structurally similar read across substance.
The reproductive toxicity of 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2)was estimated by SSS (2017) using OECD QSAR toolbox v3.3with log kow as the primary descriptor and NOAEL was estimated to be 615.55mg/kg bw. When male and female Sprague-Dawley rats were exposed with 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) orally.
Further supported by experimental study conducted byJ-check (Ministry of Health, Labour and Welfare", "Ministry of the Environment" and "National Institute of Technology and Evaluation, J-check- 2010)on structurally similar read across substance 2-Amino-5-methylbenzenesulfonic acid(88-44-8).In a Preliminary Reproduction Toxicity Screening Test, Crj:CD(SD) male and female rat were treated with 2-Amino-5-methylbenzenesulfonic acid in the concentration of 0 (vehicle), 100, 300, 1000 mg/kg/day orally by gavage in sesame oil for male consecutive 48 days of 14 days before mating and 14 days of mating period and 20 days after the end of the mating period. The female administration period was 14 days before the mating and during the mating period (maximum 14 days) and through 3 days of postpartum feeding (41 to 46 days) throughout the gestation period of the female. The females who did not deliver after copulation establishment were for 41 and 43 days up to the day before dissection on 25th gestation. Females that failed to mate were consecutive 48 days of 20 days after the mating period. No mortality was observed in treated male and female rats as compared to control. In male rats, 1 ocular secretion in the 100 mg / kg group of male, 1 hair loss in the 300 mg / kg group, 1 in the 1000 mg / kg group Crust and hair loss were observed in one case and in females, hair removal was observed in the 100 mg / kg group through pregnancy and nursing periods. In male, no effect on body weight and in female at 100 and 1000 mg / kg, statistically significant decrease in body weight were observed only on the 4th day of nursing compared to the control group. However, since there was no obvious difference on the other measurement day and it was a change only for 1 day, and since there was no obvious change in body weight gain during the nursing period, the influence of administration of the test substance It was not thought to be an accidental change. In male rats at 1000 mg/kg bw, statistically significant increase in daily food intake for the 8 to 15 days and the cumulative food consumption from 1 to 15 days and in female rats, no effect on food consumption was observed as compared to control. Similarly, No reproductive effect on copulation, implantation and sexual cycle, gestation length, number of corpora lutea or implantations, implantation index, gestation index, delivery index, purturition or maternal behaviour, numbers of offspring or live offspring, sex ratio and live birth index were observed in treated rats as compared to control. At 300 and 1000 mg/kg bw, statistically significant decrease in absolute epididymis weight were observed but no relative weight change and no effect on testicular weight were observed in treated male rats as compared to control. No gross pathological changes were attributed to the administration of the test substance. At 1000 mg/kg bw, cell infiltration of the epididymis, case in skin erosion and squamous cell epithelial hyperplasia , 1 atrophy of the thymus, 1 lung inflammation, 1 stomach ulcer and 1 part of the adrenal cortex one hypertrophy were observed in male rats. At 300 mg/kg bw, seminiferous tubular atrophy of the testes, pulmonary inflammation, 1 case in the liver necrosis and 1 atrophy of the thymus were observed in male rats. At 100 mg/kg bw, 1 Young yolk sac cysts in females who spontaneously delivered, so it was considered that there was no effect on the ovaries of the test substances. 1 Skin inflammatory infiltration and squamous epithelial hyperplasia were observed. In males and females who did not mate, seminiferous tubular atrophy of the testes was observed in males. No abnormal findings were observed in females. No abnormal findings were observed in males who did not establish pregnancy and infertile females. Atrophy of the thymus and purulent inflammation of the uterus were observed in one case in all the dead animals. No abnormal finding was observed in the other case. In addition, No effect on Viability and body weight of neonates were observed on day 0 and 4 and nonclinical sign were observed in neonates as compared to control. No abnormal findings were observed in females. At autopsy on 4th day of nursing, in the male, thymus neck remnant was 1 in the control group, 1 in the renal pelvic enlargement in the 300 mg / kg group, in the female in the control group and in the 300 mg / kg group in the renal pelvic enlargement in the kidney It was recognized in 1 and 3 cases respectively. In both cases, expression was expressed in a few cases, which was not related to administration of the test substance. Therefore, NOAEL was considered to be 1000 mg/kg/day for P and F1 generation when male and female rats treated with 2-Amino-5-methylbenzenesulfonic acid(88-44-8) orally by gavage for approx. 68 days.
Also in another experimental study conducted byU. S. Environmental Protection Agency (EPA)(U. S. Environmental Protection Agency, Hazard Characterization Document, March, 2015) on structurally similar read across substance with Sulfanilic acid (121-57-3). In a Reproduction Toxicity Screening Test, wistar male and female rat were treated with Sulfanilic acid (121-57-3)in the dose concentration of0 (water), 62.5 (50), 250 and 1000 mg/kg-bw orally by gavage in water .12 males and 12 females were placed in each dose group. Males were dosed daily for a minimum of four weeks, including a minimum of two weeks prior to mating and continued throughout the mating period until the study was terminated. Females were dosed two weeks prior to mating, until conception, throughout pregnancy and at least four days after delivery. Females showing no evidence of copulation were re-grouped with proven sires for a second mating phase. All the animals were observed for Survival, general condition, body weights, food and water consumption. At the end of the in-life phase, gross necropsy was performed, with organ mass recorded, tissues and organs preserved and processed histologically. A histopathological examination was conducted on samples from the 1000mg/kg-bw/day dose groups and the vehicle groups.
No mortality was observed in treated male and female rats as compared to control. Rats at the1000mg/kg-bw/day dose showed oronasal bleeding during the first week and occasionally throughout the study. No effects were seen on body mass as well as food and water consumption was noted. at gross necropsy, No changes in organ weights of reproductive organs were noted. Noteworthy were the statistically insignificant, mild effects on litter mass of the high dose group and on pre-implantation loss of the 250mg/kg-bw/day and 1000 mg/kg-bw/day dose group. Similarly there was a mild tendency of relatively low total numbers of pups born with increasing test item dosage and a low mean number of live pups per dam at day 4 post-partum. Hence NOAEL was considered to be 1000 mg/kg/day for P generation and LOAEL was considered to be 250 mg/kg bw /day for F1 generation, when male and female wistar rats treated with Sulfanilic acid (121-57-3) orally by gavage.
Thus, based on the above predictions and experimental study on 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) and its structurally similar read across substance No Observed Adverse Effect Level (NOAEL) was considered to be 615.55 mg/kg bw . Thus, comparing this value with the criteria of CLP regulation 2-chlorobenzene-1,4-diammonium sulphate (6219-71-2) cannot be classified as reproductive toxicant.
