Description of key information
Toxicity of test chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (CASno. 3244 -88 -0) was estimated by using OECD QSAR tool box v3.3 with log Kow as primary descriptor and considering the seven closest read across substances. When test chemical was exposed for 72 hrs on Pseudokirchneriella subcapitata (previous names: Raphidocelis subcapitata, Selenastrum capricornutum)alga, EC50 value was estimated to be 214.12 mg/L. Since EC50 value is greater than 100 mg/L it is concluded that this test chemical can be considered to be not classified according to CLP classification criteria.
Key value for chemical safety assessment
- EC50 for freshwater algae:
- 214.12 mg/L
Additional information
Studies of predicted data from different sources have been done of target chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (CAS no. 3244 -88 -0) to determine short term toxicity to green algae.
In first weight of evidence study toxicity of test chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (CAS no. 3244 -88 -0) was estimated by using OECD QSAR tool box v3.3 with log Kow as primary descriptor and considering the seven closest read across substances. When test chemical was exposed for 72 hrs on Pseudokirchneriella subcapitata (previous names are Raphidocelis subcapitata and Selenastrum capricornutum) alga, EC50 value was estimated to be 214.12 mg/L.
In another weight of evidence study the short-term toxicity of the test substance 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (CAS no.3244 -88 -0 ) to green algae is predicted using EPI Suite ECOSAR version 1.10. On the basis of effects observed in a static freshwater system during a 96 hr exposure, the effect concentration (EC50) for the substance is estimated to be 36896.191 mg/L.
Similarly, in last weight of evidence study the estimated 72 hrs EC50 value of test substance 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate (CAS no.3244 -88 -0) on Pseudokirchneriella subcapitata was determined by three different models i.e, Battery, Leadscope and SciQSAR used within Danish QSAR database. The average EC50 value was given by the third model i.e, Battery model. Based on inhibition in growth rate of test organism Pseudokirchneriella subcapitata in a static freshwater system, the estimated 72 hrs EC50 value was predicted to be 34803.73 mg/l.
Based on the results of all above studies for test chemical 2-amino-5-[(4-amino-3-sulfonatophenyl)(3-sulfocyclohexa-2,5-dien-1-ylidene)methyl]-3-methylbenzenesulfonate EC 50 value estimated was in range of 214.12 - 36896.191 mg/L therefore it is concluded that target chemical can be considered as non-toxic to green algae at environmentally relevant concentrations and can be considered not-classified as per the CLP classification criteria.
