Any other information on results incl. tables

A relatively broad endotherm was seen starting at a mean temperature of 276 °C (279.58 °C test 1, 272.69 °C test 2) suggesting boiling and decomposition. A dark brown residue remained in the crucibles at the end of the test. The thermograms are shown in Figure 11 and Figure 12 (attached).

Conclusions:

A relatively broad endotherm was seen starting at a mean temperature of 276 °C (279.58 °C test 1, 272.69 °C test 2) suggesting boiling and decomposition. A dark brown residue remained in the crucibles at the end of the test.

Executive summary:

In this guideline (OECD 103) study, [conducted with GLP certification] to ascertain the boiling point of the test substance (EC 7147-34-4), a relatively broad endotherm was seen starting at a mean temperature of 276 °C (279.58 °C test 1, 272.69 °C test 2) suggesting boiling and decomposition. A dark brown residue remained in the crucibles at the end of the test.
