- REPORTING FORMAT FOR THE ANALOGUE APPROACH
1. HYPOTHESIS FOR THE ANALOGUE APPROACH
This read-across is based on the hypothesis that the source and the target substance have very similar physicochemical and (eco)toxicological properties because their chemical structures are nearly identical. An analogue approach has thus been employed. The target substance is the meta-isomer of the dye Reactive Yellow 095, where the sulphonate group is bound at the meta-position of the amino benzene moiety. The source chemical is the reaction mass of both the meta-isomer and the para-isomer of Reactive Yellow 095.
The presence of sulphonate groups make both dyes highly water soluble and therefore less critical for human health and environmental issues. Based on their chemical similarity, similar properties are expected in both humans and the environment.
2. SOURCE AND TARGET CHEMICAL(S)
Source: Reactive Yellow 095 meta/para (CAS# --- / EC# 944-218-2)
Target: Reactive Yellow 095 meta (CAS# 84045-63-6 / EC# 281-865-3)

- Conclusions:
- The 3h-IC50 in microorganisms (activated sludge) was determined to be >320 mg/L.
- Executive summary:
The toxicity of the source substance to activated sludge was determined in a 3-hours respiration inhibition test according to the OECD Guideline No. 209. The test substance concentrations tested were 320,100, 32 and 10 mg/l. The reference substance 3,5-Dichlorophenol was tested in concentrations of 32,10 and 3.2 mg/l. The IC50 for the reference substance was found to be 13.5 mg/L. Based on the findings, the IC50 for the source substance was found to be greater than 320 mg/L
The structurally related target substance will show the same behaviour and therefore it is anticipated that the 3h-IC50 will also be >320 mg/L.

Description of key information
The 3h-IC50 in microorganisms (activated sludge) was determined to be greater than 320 mg/L.
Key value for chemical safety assessment
- EC50 for microorganisms:
- 320 mg/L
- EC10 or NOEC for microorganisms:
- 320 mg/L
Additional information
The toxicity of the source substance to activated sludge was determined in a 3-hour respiration inhibition test according to OECD Guideline 209. Based on the findings of the study, the IC50 of the source substance is greater than 320 mg/L. Two supporting studies involving different batches of the source substance have been conducted. Similar results were achieved.
The structurally related target substance will show the same behaviour and therefore it is anticipated that the 3h-IC50 will also be >320 mg/L.
