Description of key information

The boiling point of two structurally very simlar substances was determined using the Siwoloboff method according to OECD TG 103 (1995) and EU Guideline A.2 (2008). No boiling point was found. Instead, decomposition started at 225 °C (both substances) under atmospheric pressure (1027 hPa and 1030 hPa, respectively), leading to an increasingly viscous and finally solid material of yellow to brown colour. Bubbles indicated the additional formation of volatile decomposition products.
The title substance has a higher molecular weight than both reference substances. Accordingly, in view of the very similar structure it should have a higher boiling point than the reference substances if there was no decomposition, so it will not boil at atmospheric pressure before decomposition starts at approximately 225 °C.
