Key result
Test procedure:
other: Not specified
Remarks on result:
other: Pyridine-2,4-dicarboxylic 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:
Pyridine-2,4-dicarboxylic 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 Pyridine-2,4-dicarboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Pyridine-2,4-dicarboxylic acid was considered non-flammable for chemical safety assessment.
Executive summary:

Pyridine-2,4-dicarboxylic 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 Pyridine-2,4-dicarboxylic acid is not flammable at high temperature. However since such high temperatures are not found under normal circumstances of transportation and use, thus Pyridine-2,4-dicarboxylic acid was considered non-flammable for chemical safety assessment.
