Melting point / freezing point
Administrative data
Link to relevant study record(s)
- Endpoint:
- melting point/freezing point
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 17 September - 14 November 2001
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- - EEC Directive 92/69 Method A1 (1992)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.1 (Melting / Freezing Temperature)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- method to determine freezing temperature
- Melting / freezing pt.:
- < 50.5 °C
- Remarks on result:
- other: Test substance partially frozen at -50.5 degree C, but temperature did not remain constant
- Conclusions:
- No freezing point could be determined for the test substance under the current experimental conditions (freezing point < -50.5 °C ).
- Executive summary:
A GLP study was conducted according to OECD Guideline No. 102 and EC Method A1 to determine the freezing point of 2,2-bis(chloromethyl)trimethylene bis(bis(2-chloroethyl)phosphate). This study is classified as valid without restrictions and satisfies the guideline requirements.
In a first assay stirring of the test substance was not possible below -15.8 degrees C. In a second assay (without stirring) the temperature at which the test substance was partially frozen, did not remain constant. Under the experimental conditions of this test no freezing point could be determined.
Reference
- Assay 1: No freezing point was determined. The test substance was too viscous and hardened, stirring could not be performed below - 15.8 degree C (at 97.1 kPa)
- Assay 2 (without stirring): No freezing point was determined. The test substance was partially frozen at -50.5 degree C, but temperature did not remain constant.
Description of key information
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- -50.5 °C
Additional information
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.
