Description of key information

Decomposition from 248 °C, OECD 103, EU Method A.2, Fox 2012

Key value for chemical safety assessment

Additional information

In the key study (Fox, 2012), the boiling point of the test material was determined in accordance with standardised guidelines OECD 103 and EU Method A.2 using differential scanning calorimetry. Under the conditions of the study the test material was found to decompose from 248 °C at 101.3 kPa. As the test material decomposed, no value for boiling temperature could be determined. The study was conducted to GLP and was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable as an accurate reflection of the test material.

 

Supporting information is available in the form of a study in which the boiling point of the test material was determined in accordance with the standardised guideline OECD 103, by diferential scanning calorimetry. No departure from the base line of the heat flow record was recorded throughout the full temperature range from 20 °C to 250 °C. The boiling point of the test material was therefore determined to be > 250 °C. The study was conducted to agreed protocols and was assigned a reliability score of 1 in accordance with the criteria of Klimisch (1997) and considered suitable as an accurate reflection of the test material.

Furthermore, a handbook abstract (Summer, 2003) with no reported methodology, reports the boiling point of the test material to be > 250 °C. Due to it not being possible to assess the accuracy of the information, the data was assigned a reliability score of 4 in accordance with the criteria of Klimisch (1997). The supporting data are in good agreement with findings of the key study.
