EC number: 211-334-3
CAS number: 638-38-0
The density at 25°C was determined as 1.58 g/cm³.
The density of Manganese (II) acetate
tetrahydrate was reliably determined to be 1.58 g/cm³ in a study equivalent
to OECD guideline 109. Although the anhydrous form is the substance to
be registered according to the requirements under REACH, this form
practically never occurs and hence it is scientifically justified to
perform the test on the most prevalent tetrahydrat. This is supported by the
data taken from a peer-revied database which states the density to be 1.59
g/cm³. These values are nearly identical and can be explained due to
differences in the determination method and the temperature, which are not
stated in the database GESTIS.
Two independently acting literature sources
(one peer-reviewed handbook, one internet source) stated the relative
density of anhydrous Manganese acetate to be 1.74 g/cm³. Although the
magnitude of the value is plausible and the sources are reliable and
values from the two different sources are identic, the relative density
of 1.74 cm³ can be considered as potentially relevant for the anhydrate.
Another peer-reviewed source, however, stated the density of the
anhydrate to be 1.6 g/cm³. This value should be taken also into account,
especially because the density of the anhydrate is not expected to
differ that much from the values of the tetrahydrate.
In summary, the density of the tetrahydrate
of 1.58 g/cm³ is considered to be the more relevant as well as reliable
one as this is the most prevalent form of Manganese (II) acetate and ste study
was classified as Klimisch 2.
