The DSC-curve obtained with Experiment 1 is shown in Figure 1. During cooling, no effects were observed. During heating, an endothermic peak between -25 °C and 100 °C was observed. The extrapolated onset temperature of the peak was 50.482 °C. The effect was most likely obtained due to boiling of the test substance. After the experiment it was observed that the test substance had evaporated from the sample container. A higher heating rate of 50 °C/minute was applied in Experiment 2 to investigate the endothermic peak. The extrapolated onset temperature of the endothermic peak in Experiment 2 was 56.764 °C. After the experiment, it was observed that the test item had evaporated from the sample container. Experiment 3 was performed as a duplicate of Experiment 1 but without the cooling cycle. The result is similar to what was found in Experiment 1. The extrapolated onset of the boiling peak was 53.776 °C. After the experiment, it was observed that the test item had evaporated from the sample container. The difference in the extrapolated onset between Experiment 1 and Experiment 3 was > 1 °C; therefore, Experiment 4 was performed as a duplicate of Experiment 3. The extrapolated onset of the boiling peak was 53.171 °C. The boiling temperature was determined as the average obtained from Experiment 3 (53.776 °C) and Experiment 4 (53.171 °C).

Conclusions:

The boiling point of MTDID 22327 was determined as 53.5 °C at 1002 hPa as determined by EU Method A.2.

Executive summary:

The boiling point of MTDID 22327 was tested using differential scanning calorimetry (DSC) in four experiments. The boiling temperature was determined as the mean evaporation temperature of two trials done under comparable conditions. The study was conducted in accordance with EU Method A.2 and was GLP compliant; therefore the study is considered reliable without restrictions.

Executive summary:

A boiling point of 55.2 °C at 760 mm Hg for MTDID 22327 was extrapolated from data measured for the compound using the dynamic method. Vapor pressure and temperature were recorded at a variety of equilibrium points from 27.9 °C to 53.8 °C. The study was conducted following method ASTM D1120-94 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions.

Additional information

In the key study, the boiling point of MTDID 22327 was tested using differential scanning calorimetry (DSC) in four experiments. The boiling temperature was determined as the mean evaporation temperature of two trials done under comparable conditions. The study was conducted in accordance with EU Method A.2 and was GLP compliant; therefore the study is considered reliable without restrictions. In a supporting study, a boiling point of 52.3 °C at 760 mm Hg was reported. The study report cited an internal method which is similar to ATSM D1120-65. The boiling point was measured at a monitored barometric pressure and corrected to an atmospheric pressure of 760 mm Hg. The result is considered reliable with restrictions. An additional supporting study reported a boiling point of 55.2 °C at 760 mm Hg. The result was extrapolated from data measured for the compound using the dynamic method. Vapor pressure and temperature were recorded at a variety of equilibrium points from 27.9 °C to 53.8 °C. The study was conducted following method ASTM D1120-94 but was not conducted in accord with GLP guidelines; therefore, the study is considered reliable with restrictions. A third supporting study reported a boiling point range of 50 - 60 °C for MTDID 22327. Only the result was reported on an SDS and no information about the pressure or method used were provided; therefore the reliability of the data is not assignable.
