- Executive summary:
This is a GLP compliant, study following OECD guideline 102 and is considered suitable for use as the key study for this endpoint. The melting point / melting range were determined by differential scanning calorimetry (DSC) and capillary tube in a metal block.
The test item had no melting point at atmospheric conditions. Decomposition started at approx. 70 °C.
Reference
The DSC measurement in an aluminium crucible with a hole showed an exothermal effect starting at approx. 70 °C. In the temperature range of 100 – 170 °C a multistage endothermal effect was observed. After the measurement, the test item was discoloured to black. The mass loss after the DSC measurement amounted to 51 %.
An additional measurement with the capillary method was performed in order to clarify the results. A high heating rate of 10 K/min was chosen and therefore the absolute temperature values derived with the capillary method are not as accurate as the DSC results. Under consideration of the results from the DSC measurement and the capillary method it was concluded that the test item had no melting point at atmospheric conditions

Description of key information
The test item had no melting point at atmospheric conditions. Decomposition started at approximately 70 °C.
Key value for chemical safety assessment
Additional information
A GLP study following OECD guideline 102 was performed to determine the melting point of palladium (II) nitrate hydrate (Nau 2016). The study is considered reliable and suitable for use as a key study for this endpoint. It was concluded that the test item had no melting point at atmospheric conditions as decomposition started at approximately 70 °C.
