- Substance type: Organic
- Physical state: Solid Red powder - Key result
- Test procedure:
- ignition time on contact with air
- Remarks:
- Ignition on contact with air refers to either Pyrophoric solids or Pyrophoric liquids depending on physical state (migrated information).
- Remarks on result:
- no ignition on contact with air (not further specified)
- Remarks:
- corresponding to 'no' in migrated source record. | Remarks: | Additional remarks: Aluminium, 4,5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl)azo]-1H-pyrazole-3-carboxylic acid complex ignited when the flame of bunsen burner having temperature of 950 degC was brought in contact with it.
- Interpretation of results:
- other: non flammable
- Conclusions:
- From the experimental value of flammability, aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex ignited when the flame of bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex was considered non-flammable for chemical safety assessment.
- Executive summary:
From the experimental value of flammability, Aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex ignited when the flame of bunsen burner having temperature of 950 deg C was brought in contact with it. Thus it can be concluded that aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex is flammable only at high temperature of about 950 deg C. However since such high temperatures are not found under normal circumstances of transportation and use, aluminium, 4, 5-dihydro-5-oxo-1-(4-sulfophenyl)-4-[(4-sulfophenyl) azo]-1H-pyrazole-3-carboxylic acid complex was considered non-flammable for chemical safety assessment.
