Conclusions:

The study was conducted under GLP according to OECD TG 109 and EU Method A.3 without deviations and therefore reliability of Klimisch 1 has been assigned. Based on the obtained results the density of the test item Magnesium perchlorate was determined to be 2.4261 ± 0.0015 g/cm3 at 20 ± 0.2 °C.

Executive summary:

The determination of the density of Magnesium perchlorate was performed under GLP according to OECD 109 and EU Method A.3. The density was determined using the pycnometer method.

A density of 2.4261 ± 0.0015 g/cm³ at 20 ± 0.2 °C was measured. This value is the mean of two independent determinations with the maximum error of a single determination.

Standard deviation was 0.0028 g/cm³, showing good correlation of the two determinations. Therefore, the study is considered valid.

Description of key information

2.4261 at 20 ± 0.2 °C (OECD 109 and EU Method A.3, pycnometer method, GLP)

Key value for chemical safety assessment

Relative density at 20C:

Additional information

The study by LAUS (2019) was conducted under GLP according to OECD TG 109 and EU Method A.3. Based on the obtained results the density of the test item Magnesium perchlorate was determined to be 2.4261 ± 0.0015 g/cm³at 20 ± 0.2 °C. Accordingly, the relative density of magnesium perchlorate is 2.4261 (density of the test sample at 20°C to density of water at 4°C).

This result is supported by the density of 2.2 g/cm³stated for Magnesium perchlorate in the CRC Handbook of Chemistry and Physics (D.R. Lide, 2010) and the relative density of 2.21 stated for Magnesium perchlorate in Lange's Handbook of Chemistry (“Physical Constants of Organic Compounds”, 1999).
