Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- density, other
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- October 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Due to the structural similarity it can be concluded that the density of EDTA-CoH2 will not be significantly different.
- Reason / purpose for cross-reference:
- read-across source
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Type of method:
- pycnometer method
- Key result
- Type:
- density
- Density:
- >= 1.709 - <= 1.71 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- Using the pycnometer method, a density of 1.7095 ± 0.0006 g/cm3 at 20 ± 0.4 °C was measured for EDTA-CoNa2. This value is the mean of two independent determinations with the maximum error of a single determination. Standard deviation was 0.0036 g/cm3 showing good correlation of the two determinations. Due to the structural similarity it can be concluded that the density of EDTA-CoH2 will not be significantly different.
