- Storage condition of test material: at room temperature
Key result
Decomposition:
yes
Decomp. temp.:
200 °C
Remarks on result:
other: Boiling of the test substance was not observed below this temperature

During heating in Experiment 1, an endothermic peak was observed at 200 °C. After the experiment, a yellow-orange molten residue remained in the sample container. Similarly, in the preliminary TGA run at a final temperature of 274 °C, a brown residue was observed on the lid of the sample container and a brown molten residue remained in the sample container (original colour: white). Based on visual observations, this effect was most likely due to reaction and/or decomposition of the test item.

Conclusions:
Due to decomposition starting at 200 °C, MTDID 15670 has no boiling temperature as determined by EU Method A.2.
Executive summary:

The boiling point of MTDID 15670 was tested using differential scanning calorimetry (DSC). Boiling of the test substance was not observed below 200 °C (when decomposition started). Based on this, the test substance has no boiling temperature. The study was conducted in accordance with EU Method A.2 and was GLP compliant; therefore the study is considered reliable without restrictions.

Decomposition:
yes
Decomp. temp.:

Conclusions:
MTDID 15670 decomposes at a temperature of 240 °C.
Executive summary:

MTDID 15670 decomposes at a temperature of 240 °C. Only the result was reported on the MSDS and no information about the pressure or method used was provided; therefore the reliability of the data is not assignable.

Description of key information

Due to decomposition starting at 200 °C, MTDID 15670 has no boiling temperature (EU Method A.2).

Key value for chemical safety assessment

Additional information

In the key study, the boiling point of MTDID 15670 was tested using differential scanning calorimetry (DSC). The study was conducted in accordance with EU Method A.2 and was GLP compliant; therefore the study is considered reliable without restrictions. In a supporting study, MTDID 15670 was reported to decompose at a temperature of 240 °C. Only the result was reported and no information about the pressure or method used was provided; therefore the reliability of the data is not assignable.
