Additional information

A measured boiling point value of 124.4°C (397.6 K) at 1013 hPa was determined for trichloro(propyl)silane using a Photocell Detection method in accordance with OECD Test Guideline 103 and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable and is selected as key study.

The measured result is supported by a boiling point of 123.5°C at 1013 hPa which was reported for the substance in a handbook or collection of reliable data which has been subject to peer-review and in which the original sources are traceable.

In a secondary source to which reliability could not be assigned, boiling point value of 122°C at 1013 hPa was reported for the substance.
