Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Conclusions:
The freezing point of test chemical was determined as per OECD 102 adopted 27.07.95 using Micro LAB interface FS-524 data generating system and thermostat as temperature detecting system The test was conducted in replicates and mean freezing point was determined to be 12.4°C at 977 hPa.
Executive summary:

A study was performed to determine the freezing point of test chemical at respective atmospheric pressure . The study was conducted as per OECD 102 adopted 27.07.95 using Micro LAB interface FS-524 data generating system and thermostat as temperature detecting system . The mean freezing point was determined to be 12.4°C at 977 hPa.

Additional information

A study was performed to determine the freezing point of test chemical at respective atmospheric pressure . The study was conducted as per OECD 102 adopted 27.07.95 using Micro LAB interface FS-524 data generating system and thermostat as temperature detecting system . The mean freezing point was determined to be 12.4°C at 977 hPa.

In support to the key study , data from handbook indicates the freezing point to be 12.1 deg c. Also , other handbook , authoritative database and secondary source indicates the freezing point to be 12 , 12.2, and between the range of 12 -13 deg c . .
