Preliminary test
Starting at 80°C, the weight of the sample decreased significantly. At 108°C the sample weight had decreased by 25%.
After the experiment it was observed that the test item was evaporated from the sample container.
Main study
During the first experiments, no effects were observed during cooling due to crystallisation. During heating an
endothermic peak between 75°C and 125°C was observed. The extrapolated onset temperature of the peak was 114.579°C. The effect was most likely obtained due to evaporation of the test item. After the experiment it was observed that the test item had evaporated from the sample container.
After storage of the two subsamples in the freezer for 18 hours at -19.3 ± 0.6°C and at -83.5 ± 1.6°C respectively, the test item was still a liquid. According to this it was concluded that the melting temperature of the test item is < -80°C (< 193K).
Applicant's summary and conclusion
- Conclusions:
- The melting temperature of JNJ-64259884-AAA (Cyclopentylchloride) was determined to be <-80°C (193K) by applying a storage experiment in the freezer.
