- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 103 (Boiling Point)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.2 (Boiling Temperature)
- Version / remarks:
- Regulation EC No. 440/2008 Method A.2. Boiling temperature
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EPA OPPTS 830.7220 (Boiling Point / Boiling Range)
- Version / remarks:
- EPA OCSPP Test Guideline 830.7220 (1996) Boiling Point / Boiling Range
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry
- Key result
- Atm. press.:
- 1 013 hPa
- Decomposition:
- yes
- Decomp. temp.:
- >= 146 °C
- Conclusions:
- The test item Tris(hydroxymethyl)phosphine oxide (THPO) shows an evaporation of gas under decomposition, starting at 146 °C. No boiling point of the test item could be observed at atmospheric pressure (1013 hPa).
- Executive summary:
- The boiling point was determined by differential scanning calorimetry and capillary method in a GLP guideline study according to OECD 103 and EU Method A.2. The substance Tris(hydroxymethyl)phosphine oxide (THPO) shows an evaporation of gas under decomposition, starting at 146 °C. No boiling point of THPO could be observed at atmospheric pressure (1013 hPa).

Description of key information
boiling point (determined using EU Method A.2 / OECD 103; GLP):
- no boiling point of the substance Tris(hydroxymethyl)phosphine oxide (THPO) could be observed at atmospheric pressure (1013 hPa);
- THPO showed an evaporation of gas under decomposition, starting at 146 °C
Key value for chemical safety assessment
Additional information
The determination of the boiling point was carried out by differential scanning calorimetry and capillary method according to Regulation EC No. 440/2008 Method A.2. and OECD Test Guideline 103 (1995). A reliability score of 1 was assigned, in accordance with the criteria for assigning data quality in line with the principles described by Klimisch (1997).
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).
