Description of key information
The melting point of CAS# 756-12-7 is -93 °C
Key value for chemical safety assessment
Additional information
The melting point of CAS# 756-12-7 was evaluated in two studies. In the key study, the melting point was determined to be -93 °C by freezing the material in a small glass vial in a liquid nitrogen cooled isopentane bath, and then allowing natural warming of the system and observing the melting behavior in increments. This study did not follow an accepted guideline nor was conducted under GLP guidelines. Therefore, the study is considered reliable with restriction. In another study, melting point was determined to be < -80 °C which supports the key study results. Since the key study sites a specific value for melting point, rather than an upper limit for melting, a melting point of -93 °C is the preferred value. Both studies demonstrate that the test substance has a melting point less than any environmentally relevant temperature.
