Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

During this test no boiling point was observed.

Using thermal analysis, no endothermic peaks were detected in the temperature range between 25 °C and 400 °C (20 K/ min) from which boiling could be deduced. The first relevant heat effect observed is an exothermic reaction starting at about 320 °C. After the experiment, the sample had lost about 93% of its mass and the colour of the sample residue was changed to yellow.

The found result was confirmed by a second DSC measurement between 25 °C and 400 °C with a heating rate of 10 K/min.

In conclusion, the test item does not boil under ambient conditions.

Conclusions:
In conclusion, Y-15099 does not boil under ambient conditions. Decomposition (about 320 °C) of Y-15099 was observed before boiling occurred.
Executive summary:

During this test (OECD 103; differential scanning calorimetry; 25 °C- 400 °C) no boiling point was observed. In conclusion, Y-15099 does not boil under ambient conditions. Decomposition (about 320 °C) of Y-15099 was observed before boiling occurred.

After the experiment, Y-15099 had lost about 93% of its mass and the colour of the sample residue was changed to yellow.
