Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The boiling point of CAS# 756-12-7 is 26.9°C at 760 mm Hg.
Key value for chemical safety assessment
Additional information
The boiling point of CAS# 756-12-7 was evaluated in three studies. In the key study, the boiling point was determined by a static method equivalent to OECD 104 and EEC directive 92/69 EEC, Annex V, Part A.4. In the second study, the boiling point was determined to be 26 °C at 990.8 hPa and was conducted in accordance with OECD TG 103 and is compliant with GLP standards and is classified as reliable without restriction. In the third study, boiling point was determined to be 26.5 °C at 760 mm Hg which supports the key study results. The third study follows ASTM E-1719-97 and ASTM D1120-94. The key study is the preferred value due to the careful degassing steps performed by the testing laboratory. Errors in vapor pressure measurements are typically biased toward higher readings due to the effect of complications with dissolved gases such as air. This effect is exacerbated in fluids with high solubility for gases, most notably fluorochemicals such as CAS# 756-12-7.
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.
