Specific details on test material used for the study:
CAS No.: 544-31-0; EC No.: 208-867-9; Appearance: white solid at ambient temperature
Key result
Boiling pt.:
273 °C
Atm. press.:
1 013 hPa
Decomposition:
ambiguous
Decomp. temp.:
273 °C
Remarks on result:
other: mean of (271 °C; 274 °C; 274 °C)

From 273 °C the test substance shows a boiling and/or thermal decomposition with evaporation of decomposition components. The DCS measurements were confirmed with TGA measurements under the same conditions. The start of the area of boiling temperatures is defined by using the on-set temperature.

Conclusions:
Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 273 °C.
Executive summary:

A study was conducted to determine the boiling point of the test substance according to OECD Guideline 103 and EU Method A.2. Under the study conditions, the test substance shows a boiling and/or thermal decomposition earliest at ca. 273 °C (Kintrup, 2017).

Description of key information
