Specific details on test material used for the study:

SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Mr. Klemmt; E-EMD/QR - J550, Batch identification: A14-Q0201

STABILITY AND STORAGE CONDITIONS OF TEST MATERIAL
- Storage condition of test material: ambient temperature

Key result

Boiling pt.:

185.2 °C

Atm. press.:

200 hPa

Decomposition:

yes

Decomp. temp.:

ca. 197 °C

The regression of the vapor pressure data leads with a mean deviation of 2.2 % to the following (rounded) equation:

In ( p/hPa ) = 17.2078 - 4497.44 / (192.42 + t/°C )

Description of key information

In a GLP-study according to OECD Guideline 103, the standard boiling point of the test substance could not be determined. At a pressure of 200 hPa the boiling temperature was determined at 185.2 °C. At a temperature of ca. 197 °C a continuously decreasing boiling temperature at a constant pressure indicated a thermally caused change of the test substance (decomposition).
