Description of key information

Short term toxicity to fish:

In accordance with column 2 of Annex VIII of the REACH regulation, testing for this end point is considered scientifically unjustified since there are mitigating factors indicating that aquatic toxicity is unlikely to occur as the substanceChromate(1-), [2,4-dihydro-4-[(2-hydroxy-5-methyl-3-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato (2-)][3-[4-[[5-(2,2-dimethylpropyl)-2-hydroxy-3- nitrophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonamidato(2-)]-, hydrogen (72928-87-1) is highly insoluble (solubility: 0.0000000251 mg/L at 25° C) in water. Thus substancecan be considered to be hydrophobic in nature.

Short term toxicity to aquatic invertebrates:

In accordance with column 2 of Annex VIII of the REACH regulation, testing for this end point is considered scientifically unjustified since there are mitigating factors indicating that aquatic toxicity is unlikely to occur as the substanceChromate(1-), [2,4-dihydro-4-[(2-hydroxy-5-methyl-3-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato (2-)][3-[4-[[5-(2,2-dimethylpropyl)-2-hydroxy-3- nitrophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonamidato(2-)]-, hydrogen (72928-87-1) is highly insoluble (solubility: 0.0000000251 mg/L at 25° C) in water. Thus substancecan be considered to be hydrophobic in nature.

Toxicity to aquatic algae and cyanobacteria:

In accordance with column 2 of Annex VIII of the REACH regulation, testing for this end point is considered scientifically unjustified since there are mitigating factors indicating that aquatic toxicity is unlikely to occur as the substanceChromate(1-), [2,4-dihydro-4-[(2-hydroxy-5-methyl-3-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato (2-)][3-[4-[[5-(2,2-dimethylpropyl)-2-hydroxy-3- nitrophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonamidato(2-)]-, hydrogen (72928-87-1) is highly insoluble (solubility: 0.0000000251 mg/L at 25° C) in water. Thus substancecan be considered to be hydrophobic in nature.

Toxicity to microorganisms:

In accordance with column 2 of Annex VIII of the REACH regulation, testing for this end point is considered scientifically unjustified since there are mitigating factors indicating that aquatic toxicity is unlikely to occur as the substanceChromate(1-), [2,4-dihydro-4-[(2-hydroxy-5-methyl-3-nitrophenyl)azo]-5-methyl-2-phenyl-3H-pyrazol-3-onato (2-)][3-[4-[[5-(2,2-dimethylpropyl)-2-hydroxy-3- nitrophenyl]azo]-4,5-dihydro-3-methyl-5-oxo-1H-pyrazol-1-yl]benzenesulfonamidato(2-)]-, hydrogen (72928-87-1) is highly insoluble (solubility: 0.0000000251 mg/L at 25° C) in water. Thus substancecan be considered to be hydrophobic in nature.
