Description of key information

Melting point depends on the purity of the material and ranges from 54°C to 56°C 97.0-99.2%.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
54 °C

Additional information

Determination of the melting point is a standard quality control parameter. The AHTN concentration was determined with gas chromatography and the melting temperature with the capillary method. The melting point is linear related with the purity varying from 54oC to 56oC in the range of 97.0% to 99.2% AHTN.
