Rationale for reliability incl. deficiencies:
comparable to guideline study
Justification for type of information:
Experimental test result performed using standard test guidelines
Qualifier:
according to
Guideline:
other: It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source.
Principles of method if other than guideline:
It is how easily substance can burn or ignite, causing fire or combustion by brief contact with an ignition source
GLP compliance:
not specified
Specific details on test material used for the study:
- Name of test material: Pyrazinoic acid
- Molecular formula: C5H4N2O2
- Molecular weight: 124.099 g/mol
- Smiles notation: c1ncc(C(=O)O)nc1
- InChl: 1S/C5H4N2O2/c8-5(9)4-3-6-1-2-7-4/h1-3H,(H,8,9)

Key result
Test procedure:
other: not specified
Remarks on result:
other: Pyrazine-2-carboxylic acid not ignited when the flame of bunsen burner having temperature of approximately 950°C was brought in contact with it.
Interpretation of results:
other: non flammable
Conclusions:
Pyrazine-2-carboxylic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Pyrazine-2-carboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Pyrazine-2-carboxylic acid was considered non-flammable for chemical safety assessment. Flash point of pyrazine-2-carboxylic acid is predicted to be 142.1 Deg C. So GHS criteria cannot be fulfilled by pyrazine-2-carboxylic acid.
Executive summary:

Pyrazine-2-carboxylic acid does not indicate any ignition when the flame of bunsen burner having temperature of approximately 950°C is brought in contact with it. Thus it can be concluded that Pyrazine-2-carboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Pyrazine-2-carboxylic acid was considered non-flammable for chemical safety assessment. Flash point of pyrazine-2-carboxylic acid is predicted to be 142.1 Deg C. So GHS criteria cannot be fulfilled by pyrazine-2-carboxylic acid.
