Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The mean between both determinations gives the following value for the melting range:

Melting range:                                           110.1 to 111:0 °C (383.3 to 384.2 K)

Standard deviation:                                  0.1 (begin); 0:0 (end)

Estimated accuracy:                                 ± 0.2 °C

Validity

All validity criteria were met, as can be taken from the following table.

Conclusions:
The mean between both determinations gives the following value for the melting range:
Melting range: 110.1 to 111:0 °C (383.3 to 384.2 K)
Standard deviation: 0.1 (begin); 0:0 (end)
Estimated accuracy: ± 0.2 °C
Executive summary:

The melting point of the test item has been determined with a not-GLP compliant study, according to the stadard guideline OECD TG 102. Using the capillary method, the mean between both determinations gives the following value for the melting range:

Melting range:       110.1 to 111:0 °C (383.3 to 384.2 K)

Standard deviation:       0.1 (begin); 0:0 (end)

Estimated accuracy:       ± 0.2 °C
