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
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- Version / remarks:
- photocell method
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- other: Photocel method
- Specific details on test material used for the study:
- Lot# UN3261
- Decomposition:
- yes
- Decomp. temp.:
- 169 °C
- Conclusions:
- Melting point of 2-Hydroxyethyliminodi(acetic acid) was measured using photocel method following OECD 102 guidance requirements. It is not possible to determine melting point as substance is decomposing before reaching boiling point. Decomposition starts at approximately 169 C.
- Executive summary:
Melting point of 2-Hydroxyethyliminodi(acetic acid) was measured using photocel method following OECD 102 guidance requirements. It is not possible to determine melting point as substance is decomposing before reaching boiling point. Decomposition starts at approximately 169 C.
Reference
The sample was placed into a melting point capillary tube and heated in the metal block in the instrument. During the course of heating, sample decomposition was observed, which was indicated by its color change from white to a brownish color. The heating parameters used were 165 - 185°C at 0.5°C/minute. The onset of a slow color change was observed at about 169°C, indicating decomposition.

Key value for chemical safety assessment
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.
