Description of key information

The melting point of 2-chloro-p-phenylenediamine was determined according to Differential scanning calorimetry (DSC) method using Mettler Toledo, DSC 823e apparatus. The melting point of 2-chloro-p-phenylenediamine was found to be 63°C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
63 °C

Additional information

The melting point of 2-chloro-p-phenylenediamine was determined according to Differential scanning calorimetry (DSC) method using Mettler Toledo, DSC 823e apparatus. The melting point of 2-chloro-p-phenylenediamine was found to be 63°C.

Based on the data from other supporting study from various reliable sources such as handbooks (Sax's Handbook of Dangerous Industrial Materials, 2007); the melting point of 2-chloro-p-phenylenediamine was reported as 64°C which is in the range of key study value.

As the data from experimental study has K1 reliability and the test was performed in accordance with procedure AA 1020 - 1129 which has the value of melting point temperature as 63 degree C, thus considered as key study for the chemical safety assessment.
