Endpoint summary

Description of key information

The test substance is an off-white solid powder with no characteristic odour. A melting point of 141.3°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 (275°C) when tested at normal atmospheric pressure. Relative density of 1.2693 at 20°C, was measured using the pycnometer method in accordance with OECD Guideline 109. Particle size distribution was conducted using laser scattering/diffraction in accordance with ISO 13320; CIPAC MT 187. The d (0.5) was 21 µm. The vapour pressure, 6.22E-7 Pa at 20°C, was calculated using the gas saturation method in accordance with OECD Guideline 104. The partition coefficient, Log Pow, 5.08 at 20°C, was determined using the shake-flask method according to OECD Guideline 107. Water solubility of 0.000043 mg/L at 20°C, was determined using the column elution method according to OECD Guideline 105. Surface tension of 73.0 mN/m at 20°C was determined according to OECD 115. 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 per section 14.5.5 of the United Nations Transport of Dangerous Goods. The dissociation constant of the test substance could not be determined according to EPPA OPPTS 830.7370 and the pH was determined to be 6.1 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 is stable after 14 days at normal (25°C) or elevated (54°C) temperatures in the dark when tested according to the method OPPTS 830.6313. The test substance was found to be non-corrosive when tested according to ASTM method G31 72.
