Reference

Endpoint:

melting point/freezing point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

August - November 2014

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

guideline study with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.1 (Melting / Freezing Temperature)

Principles of method if other than guideline:

Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment.

GLP compliance:

not specified

Type of method:

other: differential scanning calorimetry

Key result

Melting / freezing pt.:

114 - 116 °C

Atm. press.:

1 013 hPa

Decomposition:

no

The melting point of N-Isobutyryl-thiourea was determined applying DSC. 6.2 mg test substance were put into a platen and heated up to 300°C. The onset (102°C) and the peak (109°C) of the endothermic heat fluxes were measured.

Conclusions:

The melting range of N-Isobutyryl-thiourea is 114 - 116 °C.

Executive summary:

The melting range of N-Isobutyryl-thiourea was determined applying differential scanning calorimetry. The test protocol is equivalent to the guideline EU A.01. The test substance, 6.2 mg N-Isobutyryl-thiourea, were put into a platen at room temperature and heated up to 300°C. The onset and the peak of the endothermic heat fluxes were reported. The onset of the endothermic heat flux is 102°C and reaches a peak at 109 °C. The melting range of N-Isobutyryl-thiourea was defined as 114 - 116 °C.

Description of key information

The melting range of N-Isobutyryl-thiourea is 114 - 116 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
