GLP compliance:

yes (incl. QA statement)

Type of method:

differential scanning calorimetry

Boiling pt.:

> 500 °C

Remarks on result:

other: DSC assay from 25 to 500 °C

Before the test the appearance of test item was yellow powder. After the experiments the test item became a yellow melt with bubbles and with dark brown trim around the melt.

A mass loss of 34.2 and 27.1 % was determined in the first and second experiment up to 500 °C, after the melting point, but no boiling point was recorded up to 500 °C.

Conclusions:

No boiling point was detected up to 500 °C in a DSC assay.

Executive summary:

Differential scanning calorimetry method was used. The test was carried out at normal atmospheric pressure.

Applying a linear heating rate, melting point of test item was determined to be in the range of 263.9 – 296.5 °C and no boiling point was recorded up to 500 °C.

Description of key information

No boiling point up to 500 °C.
