Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:
- 21 January to 1 February 2013
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: GLP study carried out in compliance with an internationally recognised guideline
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 102 (Melting point / Melting Range)
- 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.:
- 7.5 °C
- Decomposition:
- no
- Sublimation:
- no
- Remarks on result:
- other: In duplicate determinations, the test substance was observed to freeze at 7.5˚C (mean of 7.5˚C and 7.5˚C), as indicated by crystallisation and a plateau in the cooling curve over 5 consecutive readings (2 minutes) at this temperature.
- Conclusions:
- The freezing temperature of DMI was determined to be 7.5°C
Reference
The results for the two determinations were in good agreement (the estimated method accuracy is approximately ± 0.5˚C).
Description of key information
The freezing temperature of DMI was determined to be 7.5°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 7.5 °C
Additional information
A freezing point determination was performed as part of a package of physicochemical testing (Huntingdon Life Sciences, 2013, study LBM0053). The melting point was determined according to OECD Method 102 and EC Method A1, and the study was conducted in compliance with GLP.
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).
