Type of information:
experimental study
Adequacy of study:
key study
Study period:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.1 (Melting / Freezing Temperature)
GLP compliance:
Type of method:
differential scanning calorimetry
Specific details on test material used for the study:
Melting poit determination:
Equipment: Mettler Toledo DSC1
Conditions: temperature range: 25°C - 170°C; rate: 10°C/min
Sample weight: 5,30 mg
Key result
Melting / freezing pt.:
ca. 114.71 °C
Atm. press.:
ca. 1 atm
The test material melting point value determined by DSC analysis is: 114.71°C
Executive summary:

Melting point was determined by Differential Scanning Calorimetry (DSC) using a Mettler Toledo DSC1 operating at 25-170°C, temperature program rate 10°C/min.

Description of key information

Melting point has been determined using DSC: 114,71°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
114.71 °C

Additional information

The test material melting point value determined by two different DSC analysis is respectively 114.71°C

So, considering the accuracy of different analytical instruments, a melting point reference value for 1,3,5-tris(2,3-dibromopropyl)-1,3,5-triazine-2,4,6(1H,3H,5H)-trione can be established to be > 105°C
