Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Reference
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.

The results for the two determinations were in good agreement (the estimated method accuracy is approximately ± 0.5˚C).

Conclusions:
The freezing temperature of DMI was determined to be 7.5°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.
