Reference

Endpoint:

boiling point

Type of information:

experimental study

Adequacy of study:

key study

Study period:

2008-09-08

Reliability:

2 (reliable with restrictions)

Rationale for reliability incl. deficiencies:

comparable to guideline study with acceptable restrictions

Qualifier:

equivalent or similar to guideline

Guideline:

EU Method A.2 (Boiling Temperature)

Principles of method if other than guideline:

Differential scanning calorimetry (DSC) with a NETZSCH DSC 200 F3 instrument was used as thermal analysis method. Therefore 6.3 mg of the test substance is placed in a high pressure steel pan and heated from 30°C to 400°C with a heating rate of 5 °C/min. The reference pan is left empty.
The additional quantity of heat which is given to the sample pan in order to keep the temperature of the two pans equal is measured via a computer interface. Upon changes of the physical state the test substance absorb or emit heat, resulting in endothermic/exothermic peaks in the DCS (mW/mg) vs. temperature(°C) plot . The weight of the test substance sample is weight before and after the analysis to detect vaporatisation.

GLP compliance:

not specified

Type of method:

differential scanning calorimetry

Key result

Boiling pt.:

> 400 °C

Decomposition:

no

Remarks on result:

other: no decomposition up to 400 °C

Reduction of sample mass < 1% during anaylsis

Conclusions:

The boiling point of Caprinoguanamine is > 400°C

Executive summary:

The boiling point of Caprinoguanamine was investigated using differential scanning calorimetry (DSC). A boiling point were not identifiable and there was no reduction of sample mass in the range between 30 and 400°C. Based on these results it can be assumed that the boiling point of Caprinoguanamine is > 400°C.

Description of key information

Boiling point > 400°C

Key value for chemical safety assessment

Boiling point at 101 325 Pa:

400 °C

Additional information

The boiling point of Caprinoguanamine was investigated using differential scanning calorimetry (DSC). A boiling point were not identifiable and there was no reduction of sample mass in the range between 30 and 400°C. Based on these results it can be assumed that the boiling point of Caprinoguanamine is > 400°C. In a combustion gas analysis combustion products of Caprinoguanamine were detected at 600°C indicating a decomposition of the test substance < 600°C.
