Description of key information

The boiling point of HFP kinetic dimer is 47.3 °C at 101.325 kPa (methods ASTM D1120-94 and ASTM E 1719-97). 

Key value for chemical safety assessment

Additional information

In the key study the boiling point of HFP kinetic dimer was extrapolated using the dynamic method. The key study was conducted following methods ASTM D1120-94 and ASTM E 1719-97. The dynamic method is approved for this endpoint per OECD TG 103. In a supporting study, a boiling point of 47.6 °C at 101.325 kPa was determined using methods similar to ASTM D1120-94 and ASTM E 1719-97. The key and supporting studies were not GLP compliant and were classified as acceptable with restrictions. A third value for boiling point was found in a summary document on substance properties. However, due to few details available, it cannot be classified as to its reliability. The key study is the preferred value due to being in accordance with a guideline and having more details available than the supporting study.
