Reference
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:
read-across source
Qualifier:
according to
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.
