Description of key information
Acute Oral Toxicity:
In Acute oral toxicity ,LD50 value was predicted based on OECD QSAR toolbox for target substance Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) was estimated to be 5924.61 mg/kg bw,and for differentstudies available on the structurally similar read across substance 2-[[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulpho-2-naphthyl]azo]naphthalene-1,5-disulphonic acid (73816-75-8) was considered to be 8500 mg/kg bw and for Tartrazine (1934-21-0) was considered to be >6250 mg/kg bw. All these studies concluded that the LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) cannot be classified for acute oral toxicity.

Additional information
Acute Oral Toxicity:
In different studies, Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) 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 Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) along with the study available on the structurally similar read across substance 2-[[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulpho-2-naphthyl]azo]naphthalene-1,5-disulphonic acid (73816-75-8) and Tartrazine (1934-21-0). The predicted data using the OECD QSAR toolbox has also been compared with the experimental studies. The studies are summarized as below –
In a prediction done by SSS (2018) using the OECD QSAR toolbox with log kow as the primary descriptor, the acute oral toxicity was estimated for Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3).The LD50 was estimated to be 5924.62 mg/kg bw,when female wistar rats were orally exposed with Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) via gavage.
The above study was further supported by U.S. National Library of Medicine (Chemidplus Database,U.S. National Library of Medicine,2017) and RTECS (RTECS database ,2016) for the structurally similar read across substance 2-[[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulpho-2-naphthyl]azo]naphthalene-1,5-disulphonic acid (73816-75-8).In a acute oral toxicity study,rats were treated 1,5-Naphthalenedisulfonicacid, 2-(6-(4,6-dichlorostriazinyl) methylamino-1-hydroxy-3-sulfonaphthylazo)-)in the concentration of 8500 mg/kg bw. 50 % mortality observed in treated rats. Therefore, LD50 was considered to be 8500mg/kg bw when rats were treated with 1,5-Naphthalenedisulfonicacid, 2-(6-(4,6-dichlorostriazinyl) methylamino-1-hydroxy-3-sulfonaphthylazo)-) orally.
Also these results are further supported by Lamia A. M. Ai-Mashhedy et. al (International Journal of Pharm Tech Research,Vol.9, No.4, pp 364-367, 2016) for the structurally similar read across substance Tartrazine (1934-21-0). In a acute oral toxicity study, Sprague-Dawley male mice were treated with Tartrazine in the concentration of 0, 1250 mg/kg ,2500 mg/kg ,3750 mg/kg ,5000 mg/kg , 6250 mg/kg bw in distilled water orally via gavage and observed for 3 days. No Mortality and signs and symptoms of toxicity were observed in treated mice. Therefore, LD50 was considered to be > 6250 mg/kg bw,when Sprague-Dawley male mice were treated with Tartrazine orally via gavage.
Thus, based on the above studies on Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) and it’s structurally similar read across substances 2-[[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulpho-2-naphthyl]azo]naphthalene-1,5-disulphonic acid (73816-75-8) and Tartrazine (1934-21-0), it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3)cannot be classified for acute oral toxicity.
Justification for classification or non-classification
Based on the above experimental studies and prediction on Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) and it’s structurally similar read across substances 2-[[6-[(4,6-dichloro-1,3,5-triazin-2-yl)methylamino]-1-hydroxy-3-sulpho-2-naphthyl]azo]naphthalene-1,5-disulphonic acid (73816-75-8) and Tartrazine (1934-21-0), it can be concluded that LD50 value is greater than 2000 mg/kg bw. Thus, comparing this value with the criteria of CLP regulation, Chromate(2-), [4-[4-[(5-chloro-2-hydroxyphenyl)azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonato(3-)][4-[(5-chloro-2-hydroxyphenyl)azo]-2,4-dihydro-5-methyl-2-phenyl-3H-pyrazol-3-onato(2-)]-, sodium (90294-36-3) cannot be classified for acute oral toxicity.
