Applicant's summary and conclusion
- Conclusions:
- The freezing point of CAS# 1224866-76-5 is -28 °C
- Executive summary:
The freezing point of CAS# 1224866-76-5 was tested using both a thermal analysis method and a visual test. CAS# 1224866-76-5 was cooled down slowly in a glass tube immersed in a dry ice/acetone mixture cooling bath. The substance was judged visually and thermocouples were inserted into the sample to utilize the heat effect of a phase transformation. However, the thermocouples showed no heat effect from which freezing could be deduced, and the phase transformation was determined visually. The freezing point was determined to be -28 °C.
According to OECD 102, the freezing temperature method is considered accurate for determining melting/freezing point down to -50 °C. Although the sample wasn't continuously stirred, the sample was observed in terms of its viscosity and the value is relevant to the endpoint. This study is conducted in accordance with OECD 102 and GLP guidelines. Therefore this study is considered valid without restrictions.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
