Description of key information

Additional information

The test item is yellow solid at ambient temperature.

The melting point was found to be in the range 37.2 to 39.4 °C (310.3 to 312.5 K) by differential scanning calorimetry and the boiling point was not determined as the tets item decomposed from approximately 250.6 °C (523.7 K) prior to boiling at 101.2 kPa.

The density was determined to be 1.21 x 103 kg/m3 at 20.0 ± 0.5 °C, using the a gas comparison pycnometer.

The proportion of test item having an inhalable particle size of less than 100 μm was determined by a sieve method to be 6.76%.

Using Vapor method, the vapor pressure was found to be less than 2.3 x 10-3 Pa at 25 °C.

The water solubility of the test item was determined to be 0.33 mg/L @ 20 °C using the column elution method and the partition coefficient of the test item has been determined as log P  0.969 to > 6.5 (95.8% having a log10 Pow of 4.46) (HPLC method).

The surface tension study does not need to be conducted because Water Solubility is below 1 mg/L at 20°C and the flash point was also waived because of the physical state of the test item. Flash point is only a relevant property for liquids.

The self-ignition temperature was determiend to be 530 ± 5 °C and the test item is not flammable. Oxidising properties and explosives properties turned out to be all negatif due to the chemival structure of the test item.
