- Qualifier:

- Qualifier:

- Deviations:

- Principles of method if other than guideline:
- The above-mentioned guidelines contain several different methods for the determination of the melting point / melting range and the boiling point / boiling range. These are between others, thermal analysis using a calorimeter and visual tests (e.g. capillary method), where the melting resp. freezing temperatures as well as the boiling temperature are measured. In the present study the thermal analysis was applied.
A phase transformation, e.g. melting or evaporation, or a reaction, e.g. dissociation, usually is associated with a heat effect.
In the calorimeter, two identical aluminium sample containers, one filled with the test item and the other empty (used as the reference), were heated at a constant rate. During the experiment, the heat effect, i.e. the difference in heat flow between the sample container and the reference container, was registered. - GLP compliance:
- yes (incl. QA statement)
- Type of method:
- differential scanning calorimetry

RESULTS
The determination of the boiling point / boiling range of the test item was performed according to the EEC Directive 9 A.2 “Boiling temperature”, December 1992 and to the OECD Guideline No. 103: “Boiling Point”, adopted July 27, 1995.
Preliminary Test
The DSC-curve of the preliminary test (heating rate of 20 K/min from 25°C to 400°C) showed that there was no peak observed from which boiling of the sample could be deduced. After the experiment, the sample had lost about 69 % of its mass and the sample was black and carbonized.
Boiling Point
Using thermal analysis, no endothermic peaks were detected in the temperature range between 25°C and 400°C from which boiling could be deduced. During the preliminary test, an endothermic heat effect, the melting of Tosylfuranosid was observed at about 67.5°C. Starting at about 160°C an exothermic reaction was observed. The exothermic reaction was caused by the decomposition of the test item. After the experiment the test item was black and carbonized.
A second DSC run was performed to confirm the result found during the preliminary test.
In conclusion, the decomposition of Tosylfuranosid was observed before boiling occurred.
Applicant's summary and conclusion
- Conclusions:
- During this study the boiling point of Tosylfuranosid was determined.
No boiling point could be determined as decomposition of Tosylfuranosid was observed before boiling occurred. - Executive summary:
Using thermal analysis, no endothermic peaks were detected in the temperature range between 25°C and 400°C from which boiling could be deduced. During the preliminary test, an endothermic heat effect, the melting of Tosylfuranosid was observed at about 67.5°C. Starting at about 160°C an exothermic reaction was observed. The exothermic reaction was caused by the decomposition of the test item. After the experiment the test item was black and carbonized.
A second DSC run was performed to confirm the result found during the preliminary test.
In conclusion, the decomposition of Tosylfuranosid was observed before boiling occurred.
