Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:

 Endpoint  Data
 Appearance (visual)

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

 Melting point (OECD 102/EU A1, DSC)

The melting point of the test item was recorded at 129.0 °C ± 0.5 °C

Boiling point (OECD 103/EU A2, DSC) 

No boiling point was recorded. A black residue was observed in the crucible.

 Density (OECD 109/EU A3, pycnometer)

 The density of test item was determined to be 1097.6 kg/m3 at 24.9°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 742 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)

The study does not to be conducted because the substance is a solid having a melting point ≤160°C

 Flash-point (waiving)

 The flash point of test substance was waived (The study does not to be conducted because the flash point is only relevant to liquids and low melting point solids)

 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 beacause the substance is a lyophylisate
 Organic peroxides (waiving)  Not a peroxide
 Self reactive substances (waiving)  Not a self reactive substance
