Endpoint summary

Administrative data

Description of key information

Physico-chemical endpoints are completed based on test data following standard guidelines and data waivers. All data are therefore considered to be reliable and relevant for the endpoint concerned.

 

Appearance / Physical state / Colour

The test item is a white solid at room temperature as reported in the test item section of a GLP-compliant experimental study (Dunning 2018).

 

Melting point/freezing point

The melting temperature of the test item was not determinable as the test item decomposed at temperatures before melting, the decomposition temperature was determined to be 325 °C (Dunning 2018). The study was conducted according to OECD 102 and EU Method A.1 guidelines.

 

Boiling point

This endpoint was waived in accordance with column 2 of REACH Annex VII. The boiling point study does not need to be conducted as this substance decomposes before boiling.

 

Density

The relative density was determined to be 1.42 at 20°C (Dunning 2018). The study was conducted according to OECD 109 and E.U. Method A.3 guidelines.

 

Particle Size Distribution

This endpoint was waived in accordance with column 2 of REACH Annex VII. The granulometry study does not need to be conducted as the substance is marketed or used in a non-solid or granular form.

 

Vapour Pressure

The vapour pressure of the test item was determined to be <1 x 10-07 Pa at 25°C (Dunning 2018). The study was conducted according OECD Method 104 and EC. Method A.4 guidelines.

 

Partition coefficient

The partition coefficient (Log Pow) of the test item was determined to be <1 (Dunning 2018). The study was conducted according OECD Method 117 and EC. Method A.8 guidelines.

 

Water Solubility

The water solubility of the test item was determined to be 1.52 ± 0.03 g/L at 20°C (Dunning 2018). The study was conducted according OECD Method 105 and EC. Method A.6 guidelines.

 

Surface Tension

The test item was found to have a surface tension of 72.5 mN/m (Dunning 2018). The study was conducted according OECD Method 115 and EC. Method A.5 guidelines.

 

Flashpoint

This endpoint was waived in accordance with ECHA Guidance on information requirements and chemical safety assessment, Chapter R7a: endpoint specific guidance. The flash point study does not need to be conducted as this substance is a solid at room temperature.

 

Auto flammability

The test item ignited by self-heating at a temperature of 390°C (Dunning 2018). The study was conducted according to E.U. Method A.16 guideline

 

Flammability

The test item was found to be not highly flammable (Dunning 2018). The study was conducted according to E.U. Method A.10 guideline.

 

Explosiveness

This endpoint was waived in accordance with column 2 of REACH Annex VII. The explosive properties studies do not need to be conducted as there are no chemical groups associated with explosive properties present in the substance.

 

Oxidising Properties

This endpoint was waived in accordance with column 2 of REACH Annex VII. The oxidising properties study does not need to be conducted as the substance is incapable of reacting exothermically with combustible materials on the basis of the chemical structure.
