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:
- 22 January 2014
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- comparable to guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: EU Method A.2 (boiling temperature)
- Deviations:
- no
- GLP compliance:
- not specified
- Type of method:
- capillary method
- Remarks:
- using a Melting temperature devices with metal block and photocell method
- Specific details on test material used for the study:
- SOURCE OF TEST MATERIAL
- Source and lot/batch No.of test material: Polytec International Ltd. (Lot number: 20131012) - Key result
- Decomposition:
- yes
- Decomp. temp.:
- >= 120
- Remarks on result:
- other: The onset of a slow color change was observed at about 120°C, indicating decomposition. The sample remained solid and melting of the sample did not occur.
- Conclusions:
- The melting point value of ferrous gluconate could not be determined due to decomposition of the substance, as noted by a change in color. The reliable study of melting point was conducted according to the appropriate standard test methods EU Method A.2 (Boiling point) and OECD Guideline 102 (Melting point/melting range).
Reference
The onset of a slow color change was observed at about 120°C, indicating decomposition. The sample remained solid and melting of the sample did not occur.
Description of key information
EU Method A.2 (Boiling point)/OECD Guideline 102 (Melting point/melting range)
The decomposition temperature was determined to be higher than 120°C.
Key value for chemical safety assessment
Additional information
A melting point value of ferrous gluconate could not be determined due to decomposition of the substance, as noted by a change in color. The reliable study of melting point (Baldwin, 2014, Melting Point and Boiling Point of Iron Gluconate) was
conducted according to the appropriate standard test methods EU Method A.2 (Boiling point) and OECD Guideline 102 (Melting point/melting range).Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
