- Specific details on test material used for the study:
- - Batch n°: RT002102G4A311
- Analytical purity: 99.4%
- Expiration date: 25 March 2002
- Storage condition: at room temperature - Key result
- Boiling pt.:
- > 252 °C
- Decomposition:
- yes
- Decomp. temp.:
- ca. 252 - < 300 °C
- Remarks on result:
- other: Decomposition started at about 252 deg C, the color of the sample changed to dark brown and at about 256 deg C the sample expanded, changed its color to black and solidified.
- Conclusions:
- The test substance does not boil under the conditions of the test. Decomposition occurs prior to boiling.
Reference
In the preliminary test, at 256 deg C the test substance started to expand and at 300 deg C the sample changed its color to black. At the end of the test the sample was colored black and solidified. These observations were due to the decomposition of the test substance. The boiling point of T002102 was not detectable.
In a confirmatory main test, decomposition started at about 252 deg C. The color of the sample changed to dark brown and at about 256 deg C the sample expanded, changed its color to black and solidified.
Description of key information
A GLP study was performed according to OECD guideline 103 and EU Method A.2 (Tognucci, 2002) in which no boiling point was determined due to the fact the substance decomposed before boiling.
Key value for chemical safety assessment
Additional information
The GLP study of Tognucci (2002) to determine the boiling point of T002102 was performed according to OECD guideline No. 103 and EEC Directive 92/69, A.2 and concluded that the substance does not boil under the conditions of the test and decomposed before boiling. Decomposition started at 252°C. This study is considered reliable (Klimisch 1) and assigned as key study for this endpoint.
