Conditions: Sample weight: ~11mg; Start temp: 35.0°C; Rate: 10.0°C/minute; Gas: N2

GLP compliance:

no

Type of method:

thermal analysis

Remarks:

Differential scanning calorimeter (DSC) and optical melting determination

Melting / freezing pt.:

>= 46 - <= 74 °C

Atm. press.:

1 atm

Decomposition:

no

Sublimation:

no

Remarks on result:

other: The thermogram shows a endothermic phase transition from solid to liquid (lined peak)

Melting / freezing pt.:

>= 50 - <= 57.2 °C

Atm. press.:

1 atm

Decomposition:

no

Sublimation:

no

DSC determination: The full thermogram view is difficult for interpretation so an enlargement of the segment between 46-74oC was performed. A endothermic phase transition from solid to liquid (lined peak related to the Melting Range. Melting Range:52.5-68.5oC.

The thermogram shows a endothermic phase transition from solid to liquid (lined peak).

Onset result is more specifically related to the physically change -Melting Point since it is not influenced by sample size and scan rate.

Onset: 53.63°C

Max Peak: 60.77°C

Optical Melting determination: Range: 50.2 -57.2°C. Point: 52.4 °C

Conclusions:

The thermogram shows a endothermic phase transition from solid to liquid (lined peak related to the Melting Range).
Melting Range:52.5-68.50C and Max Peak: 60.77°C
