GLP compliance:
no
Parameter:
other: Explosive (not specified)
Remarks on result:

Interpretation of results:
non explosive
Remarks:
Migrated information
Conclusions:
The substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
Executive summary:

In summary, analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore the substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.

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)

Description of key information

The substance is considered to be non-explosive.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

Analysis of the chemical structure reveals no alerts for explosive properties. The calculated chemical oxygen balance is above the trigger value of -200, but the determination of the exothermic decomposition energy demonstrated an energy release far below the critical value of 500 J/g. Therefore the substance is considered to be non-explosive according to Regulation (EC) 1272/2008 and no further testing is required.

Justification for classification or non-classification

The substance is considered to be non-explosive according to Directive 67/548/EEC and Regulation (EC) 1272/2008 and no further testing is required.
