- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 11 Sept - 6 Nov 2002
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with generally accepted scientific standards and described in sufficient detail
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: thermal analysis and melt microscope
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Batch No.of test material: K100
- Sample no./year: 1069024/2002
- Purity: 98.7%
- Expiration date of the lot/batch: August 12, 2004 - Key result
- Melting / freezing pt.:
- > 280 °C
- Decomposition:
- no
- Conclusions:
- The melting point of PFBSK+ is > 280 °C according to EU Method A.1.
- Executive summary:
Under a melting point microscope, no liquidification up to a temperature of 280 °C could be observed. The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions.
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Qualifier:
- no guideline followed
- GLP compliance:
- no
- Key result
- Melting / freezing pt.:
- 270.4 °C
- Conclusions:
- The mean melting point for PFBSK+ is 270.4 °C.
- Executive summary:
The mean melting point of 270.4 °C for PFBSK+ is 270.4 °C in an average of three determinations performed on three lots of the title compound. No further details were reported and no information about the pressure or method used was provided; therefore the reliability of the data is not assignable.
- Endpoint:

Description of key information
The melting point of PFBSK+ is > 280 °C according to EU Method A.1.
Key value for chemical safety assessment
Additional information
Under a melting point microscope, no liquidification of PFBSK+ up to a temperature of 280 °C could be observed. The study was conducted in accordance with EU Method A.1 and was GLP compliant; therefore the study is considered reliable without restrictions. In two supporting studies, the melting point of PFBSK+ was determined to be 271 - 275 °C and 270.4 °C. The reports only included the result and no information about the pressure of method used were provided; therefore the reliability of the data is not assignable.
