- 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 Blue 049, where the sulphonate group is bound at the meta-position of the aminobenzene moiety. The source chemical is the reaction mass of both the meta-isomer and the para-isomer of Reactive Blue 049.
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 Blue 49 meta/para (CAS# 72214-18-7 / EC# 276-481-8)
Target: Reactive Blue 49 meta (CAS# 72927-99-2 / EC# 277-040-2)
3. ANALOGUE APPROACH JUSTIFICATION
see attachment under 4.2 Melting point / freezing point - Reason / purpose for cross-reference:
- read-across source
- GLP compliance:
- no
- Key result
- Test procedure:
- burning rate test: preliminary screening test
- Burning time:
- 0 s
- Remarks on result:
- substance does not ignite and propagate combustion either by burning with flame or smouldering along 200 mm of the powder train within the 2 minutes test period
- Interpretation of results:
- non flammable
- Remarks:
- Migrated information
- Conclusions:
- No ignition was observed throughout the course of the test. The test item should be considered as not highly flammable.
- Executive summary:
The determination of the flammability of the test item was performed in accordance with the EEC Directive Annex V of 67/548 Test A 10 Flammability (Solids).
A preliminary screening test was performed to determine if an ignition by a gas flame, propagation by burning with flame or smouldering occurs. For this purpose the test item was formed into an unbroken strip or powder train about 250 mm long. If propagation over 200 mm of the train occurs within a specified time, then a full test programme to determine the burning rate has to be carried out.
The test item was heated with the flame of a teclu burner. Glowing was observed during heating. No ignition occurred within two minutes.
Since ignition did not occur within two minutes, the test item was classified as not highly flammable and no determination of burning rate was necessary.
The test item should hence be considered as not highly flammable.

Description of key information
The substance is not highly flammable.
Key value for chemical safety assessment
- Flammability:
- non flammable
Additional information
The determination of the flammability of the source substance was performed in accordance with the EEC Directive Annex V of 67/548 Test A 10 Flammability (Solids). Since ignition did not occur within two minutes, the source substance was classified as not highly flammable and no determination of burning rate was necessary. The structurally related target substance should hence also be considered as not highly flammable.
Justification for classification or non-classification
No ignition was observed throughout the course of the test.
The test item should be considered as not highly flammable.
