Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Boiling point: Decomposition from about 128°CKey value for chemical safety assessment
- Boiling point at 101 325 Pa:
- 320 °C
Additional information
The boiling point of the substance was determined using photocell detection and thermal analysis (DSC/TGA) methods in accordance with OECD 103. 3-[Tris(acetoxy)silyl]propyl methacrylate was observed to undergo thermal decomposition, degradation or rearrangement from about 128°C, colour change from transparent clear liquid to slight yellowish liquid, at about 215°C boiling was observed. The result is considered to be reliable and selected as key study.
In addition, a boiling point of 320°C was predicted for 3-[tris(acetoxy)silyl]propyl methacrylate using a validated QSAR method. The prediction does not account for the potential for the submission substance to undergo decomposition, degradation or rearrangement, but it is considered sufficient to indicate the theoretical boiling point of the substance without decomposition and it is used as a supporting study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
