Additional information

 

The test substance is a solid.

The melting point is 142.0°C, measured using a capillary apparatus (DuPont 18633-1644).

The boiling point is 274.0°C and was measured according to ASTM Method D1120 (DuPont 18633-1644).

Density is 0.726 g/mL and was measured according to ASTM Method No. E-727 (DuPont 18633-1644).

Granulometry measurements have been conducted. Approximately 3.8% of the particles were less than 180 µm by sieving (DuPont 18633 -1644).

The vapour pressure is 1.04E-2 Pa at 20°C and was measured according to OECD Guideline 107 by the spinning rotor method (DuPont-18633-394).

The octanol/water partition co-efficient (log Pow) is -0.839, measured in accordance with OECD Guideline 107 by the shake-flask method (CIT Study No. 29566 APC).

The water solubility is reported as 31000 mg/L at 20°C. The measurement was performed according to OECD Guideline 105 and the solution was alkaline and brown (CIT study No. 30449PSE).

The surface tension of a 1 g/L solution at 20°C is 80.0 mN/m, measured according to OECD Guideline 115 (DuPont 18633-1644).

No flash point measurement was conducted. In accordance with Section 2 of REACH Annex XI, information requirement section 7.9, flash point does not need to be conducted based on the physical state of the molecule. According to ECHA guidance, flash point is only relevant to liquids and low melting solids.

No auto-ignition study was conducted. In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.12, this study does not need to be conducted for solids with melting points less than 160°C.

The test substance did not ignite during the full 2 minutes of heating when tested according to EC Method A.10. Therefore, the material is not highly flammable (DuPont-18633 -1644).

The test substance is non-explosive. In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.11, explosivity testing does not need to be conducted based on a structural assessment of the substance. Examination of the structure indicates that there are no groups associated with explosive properties.

The test substance is non-oxidising. In accordance with Column 2 adaptation statement of REACH Annex VII, information requirement section 7.13, this measurement of oxidising properties does not need to be conducted based on structural assessment of the substance. The substance contains no oxidising groups.

Measurement of stability in organic solvents was waived.In accordance with REACH Annex XI Section 2, with reference to the guidance mentioned in REACH Art 13(3) the test guidance "ECHA guidance on Information requirements and chemical safety assessment Chapter R.7a Endpoint specific guidance" needs to be respected. This guidance indicates that this study does not need to be conducted since the stability in organic solvents is not considered critical. This would be assessed in individual studies where organic solvents are used.

The dissociation constant, 6.22, was calculated using equations included in "pKa Prediction for Organic Acids and Bases” (Perrin, et al, 1981).

Measurement of viscosity was waived. In accordance with Section 2 of REACH Annex XI, information requirement section 7.17, this study cannot be conducted on solid materials. According to ECHA Chapter 7 guidance, viscosity measurement is only relevant to liquids.
