Description of key information
Appearance:
Chemical pyridine-2,4-dicarboxylic acid physically appear as a solid crystal.
Melting point:
Melting point of pyridine-2,4-dicarboxylic acid is determine to be 249 Deg C.
Boiling Point:
Boiling point of pyridine-2,4-dicarboxylic acid is determine to be 295.67 Deg C.
Density:
Density of pyridine-2,4-dicarboxylic acid is determine to be 1.5216 g/cm3 at temperature 25 C.
Particle size distribution:
The particle size distribution of Pyridine-2,4-dicarboxylic acid was determined by granulometric analysis with rotap sieve shaker. The particle size distribution was determined to be in the range of 150 micron to 25 micron.
Vapour pressure:
Vapour pressure of pyridine-2,4-dicarboxylic acid is determine to be 0.00081 Pa at 25 Deg C.
Partition coefficient:
Based on the available data from handbook and authoritative databases, the partition coefficient (log Pow) value of the substance2,4-Pyridinedicarboxylic acidwas estimated to be 0.57. Based on the estimated value, chemical 2,4-Pyridinedicarboxylic acid can be considered to be hydrophilic in nature.
Water solubility:
Water solubility of chemical pyridine-2,4-dicarboxylic acid is determine to be 2490 mg/L at temperature 25 C.
Surface tension:
Based on the data from ACD labs, surface tension for Pyridine-2,4-dicarboxylic acid was predicted to be 0.0835 N/m.
Flash point:
Flash point of Pyridine-2,4-dicarboxylic acid is estimated to be 301.25 Deg C.
Auto flammability:
Pyridine-2,4-dicarboxylic acid did not catch fire on being exposed to air at room temperature of 27°C pressure of 966 hPa. This indicates that Pyridine-2,4-dicarboxylic acid is not auto-flammable.
Flammability:
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.
Explosiveness:
The study does not need to be conducted because there are no chemical groups present in the molecule which are associated with explosive properties.
Oxidizing properties:
The study does not need to be conducted because the substance is a solid.
