Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 melting point of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 102. The test item showed a melting range, no defined melting point. As the test item consists of a mixture of two components, this is considered as normal. A slight residue was observed, also. It is believed that this belongs to an impurity. No observations were made which might cause doubts on the validity of the study outcome. The melting range was determined as 94.5 to 121.9 °C (367.7 to 395.1 K). These values are the means of two independent determinations.
Executive summary:

The melting point of N-[(3(5)-Methyl-1 H-pyrazol-1 -yl)-methyl]acetamide was determined according to OECD guideline 102. The test item showed a melting range, no defined melting point. As the test item consists of a mixture of two components, this is considered as normal. A slight residue was observed, also. It is believed that this belongs to an impurity. No observations were made which might cause doubts on the validity of the study outcome. The melting range was determined as 94.5 to 121.9 °C (367.7 to 395.1 K).
