Description of key information

Physico-chemical properties of registered substance were determined from experimental testing. Some endpoints were waived, based on chemical structure.

The substance is a yellow powder at ambient temperature, with low volatility. It is soluble in water.

Surface-active properties are not expected.

It has no potential for bioaccumulation (log Kow<0.3).

It is not classified as hazardous with regard to physical hazards (flammability, explosivity, oxidising properties) based on CLP criteria.

Summary of relevant physico-chemical properties:

 End points  Data
 Appearance (visual)

 Registered substance is a yellow powder at 20 °C and 1 atm.

 Melting point (OECD 102/EU A1, DSC)

 No melting point was recorded up to 600°C, a decomposition of the test item was recorded after

the experiment.

 Boiling point (OECD 103/EU A2, DSC)

 No boiling point was recorded up to 600°C, a

decomposition of the test item was recorded after

the experiment.

 Density (OECD 109/EU A3, pycnometer)

 The density of test item was determined to be 1560.0 kg/m3 at 20.1°C


Vapour pressure (OECD 104/EU A4, effusion method weight loss)

The vapour pressure of the test item is largely lower than 10-3 Pa at 20 °C.


 Log Kow (OECD 117, A24,HPLC method)

 The partition coefficient n-octanol/water of the test

item was stated as < 0.3

 Water solubility (OECD 105, A6, flask method)

 The water solubility was determined as 780.3 g/L at 30°C (pH=5).

 Surface tension (waiving)

 Waiving (based on structure, surface activity is not expected and surface activity is not a desired property of the material)

 Self-ignition temperature (waiving)

 Based on the weight of evidence approach, no selfignition

is expected for this substance

 Flash-point (waiving)

 The flash point of test substance was waived (The

study does not to be conducted because decomposition of the test item occured during the melting point study

 Flammability (EU A10/UN method N1)

 Not considered to be flammable.

No ignition in contact with flame. No propagation in

contact with a flame: not a flammable solid (CLP/GHS)

No hazardous reaction anticipated if contact with

air or water, based on chemical structure and experience in handling and use.

Explosive properties(data waiving, based on chemical structure)

Neither explosive nor self-reactive properties are anticipated

 Oxidising properties (data waiving)

No oxidising properties are anticipated 

 Particle size distribution (data waiving)

 The study does not need to be conducted because the substance is a lyophylisate

 Organic peroxides (waiving)

 Not a peroxide

 Self reactive substances (waiving)

 Not a self reactive substance
