Remarks on result:
other: Freezing point=less than -13.5 °C
Conclusions:
The Freezing point of 3,7-dimethylocta-2,6-dienenitrile(CAS No. 5146-66-7) was determined using crushed ice and salt.
No freezing was observed up to -13.5 °C at 965.9 hPa.
Executive summary:

In an experiment conducted by SSS (Europe) AB,the Freezing point of 3,7-dimethylocta-2,6-dienenitrile (CAS No.5146-66-7)was determined with crushed ice and salt bath and the freezing point was concluded to be less than-13.5°C at 965.9 hPa.

Description of key information

In an experiment conducted by SSS (Europe) AB,the Freezing point of 3,7-dimethylocta-2,6-dienenitrile (CAS No.5146-66-7)was determined with crushed ice and salt bath and the freezing point was concluded to be less than-13.5°C at 965.9 hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-13.5 °C

Additional information

In an experiment conducted by SSS (Europe) AB,the Freezing point of 3,7-dimethylocta-2,6-dienenitrile (CAS No.5146-66-7)was determined with crushed ice and salt bath and the freezing point was concluded to be less than-13.5°C at 965.9 hPa.

Other supporting studies from reliable sources such as authoritative database and review article also suggeest that the freezing point value of chemical 3,7-dimethylocta-2,6-dienenitrile determined to be in the range of -7.79 degree C to <-50 degree C.

As the data from lab has K1 reliability and the test was performed using standard methods of analysis which has the value of freezing point as < -13.5 degree C thus considered as key study for the chemical safety assessment
