Endpoint summary

Description of key information

The test substance is an off-white to beige powdery solid with no characteristic odour. A melting point of 106.0-107.5°C was determined using the capillary tube method according to OECD Guideline 102. A boiling point of the test substance was not observed prior to its decomposition point (339°C) when tested at normal atmospheric pressure. Relative density of 1.56 at 21°C, was measured using the pycnometer method in accordance with OECD Guideline 109. The vapour pressure, 1.2E-5 Pa at 20°C, was calculated using the vapour pressure balance method in accordance with OECD Guideline 104. The partition coefficient, Log Pow, 5.1 at 20°C, was determined using the shake-flask method according to OECD Guideline 107. Water solubility of 0.11 mg/L at 20°C, was determined using the column elution method according to OECD Guideline 105. Particle size distribution was conducted using laser scattering/diffraction in accordance with OPPTS 830.7520. The median diameter was 78 µm. The test substance was not flammable in a test following EU Method A.10. No ignition was detected before the sample melted in an auto-flammability test conducted according to EU Method A.16. The dissociation constant of the test substance was determined to be 3.56 when tested according to OECD Guideline 112 and the pH was determined to be 9.0 when tested according to method OPPTS 830.7000. The substance is non-explosive based on results from a study conducted according to EU Method A.14 and is not oxidising based results from a study conducted according to EU Method A.17. The test substance has no oxidation and reduction potential when tested according to the method OPPTS 830.6314. The test substance is stable in the presence of metals and metal ions upon 14 days of storage when tested according to the method OPPTS 830.6313.
