Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Melting point (chloromethyl)triethoxysilane: < -20°C (predicted)

Key value for chemical safety assessment

Additional information

The melting point of the substance is predicted to be well below -20°C on the basis that it has a measured boiling point of 200°C (473K) and the number of atoms in the side-chain (discounting hydrogen atoms) is ≤10. A review of data for organosilicon compounds has indicated that alkoxysilane substances that meet these two conditions: boiling point is <600K (ca. 330°C) and the number of atoms in the side-chain (discounting hydrogen atoms) ≤10 are expected to have a melting point < -20°C. Additional information is given in a supporting report (PFA, 2013ag) attached in Section 13 of REACH technical dossier.
