- Executive summary:
A study was conducted according to OECD test guideline 103, Regulation (EC) No 440/2008 method A.2 to determine the boiling point of the test item using differential scanning calorimetry. The test item was weighed out into an aluminium crucible under an inert atmosphere (nitrogen). Two tests with about 11 – 21 mg of the test item were performed. As reference crucible, an empty aluminium crucible was used. The substance is a waxy solid at ambient conditions. The crucibles were heated up from room temperature to 500 °C and 280 °C respectively. Two DSC measurements showed an ambiguous endothermal effect after the melting in the temperature range of 260 - 280 °C. An additional measurement with the capillary method was performed in order to clarify the boiling range. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen. The filling height of the test item was approximately 5 mm. Under consideration of the results from the DSC measurements and the capillary method it was concluded that the test item started to decompose under possible boiling above 200 °C.

capillary tube in a metal block
A measurement with the capillary method was performed to clarify the results of the DSC measurements. Since this measurement was performed only as a verifying screening a high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. The filling height of the test item was approximately 5 mm.

The test item was a waxy solid. According to information from the sponsor it tends to be inhomogeneous with small inclusions of solvent. Under consideration of the results from the DSC measurements, the capillary method and the aforementioned properties it was concluded that the test item exhibited a phase transition around 80 °C (value is subject to a uncertainty of approx. 10 K due to high heating rate). The observed bubbles could have been caused by the release of minor quantities of residual solvent (see also certificate of analysis). The formation of bubbles above 200 °C might indicate boiling or decomposition or both. Under consideration of the results from the DSC measurements and the capillary method it was concluded that the test item started to decompose under possible boiling above 200 °C.
Description of key information
The test item started to decompose under possible boiling above 200 °C (reference 4.3-1).
