Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Type of information:
experimental study
Adequacy of study:
key study
Study period:
2018
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
comparable to guideline study with acceptable restrictions
Qualifier:
no guideline followed
Principles of method if other than guideline:
An automatic gas pycnometer was used to determine the density of the substance, which was tested 1. 'as received' and 2. after drying at 200°C for 16 h under vacuum. Drying yielded a 1.7 wt-% loss.
Each sample was objectd to 10 analyses/test cycles.
GLP compliance:
no
Type of method:
air comparison pycnometer (for solids)
Specific details on test material used for the study:
TREATMENT OF TEST MATERIAL PRIOR TO TESTING
A portion of the substance was dried at 200°C for 16 h under vacuum prior to the density investigations.
Besides the dried sample, a sample of the substance 'as received' was tested.
Dynamic viscosity of test material:
not applicable (substance is a solid)

The systematic error is estimated at ≤ 1% relatively.

Since the systematic error is estimated at < 1% relatively, the maximum absolute error obtained over these samples is approx. 0.03 g cm-3.

Conclusions:
The density of the substance was determined to be 3.035 g/cm3 (at 25°C).
Executive summary:

The density of the (dried) solid substance was determined to be 3.035 g/cm3 (at 25°C using a gas comparison pycnometer).

Description of key information

The density of the substance was determined to be 3.035 g/cm3 (at 25°C).

Key value for chemical safety assessment

Additional information

Determined in a study comparable to a guideline study using an automatic gas pycnometer and dried sample.
