Endpoint:
relative density
Type of information:
experimental study
Adequacy of study:
key study
Study period:
2017-06-27 until 2017-08-29
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
OECD Guideline 109 (Density of Liquids and Solids)
Qualifier:
according to
Guideline:
EU Method A.3 (Relative Density)
Principles of method if other than guideline:
Since the test item is a solid melt at room temperature it could not be filled in a pycnometer. For this reason the test item was melted, filled in a glass vial and weighed. The volume of vial was determined before and the density of the test item could be calculated with the quotient of sample weight and the corresponding volume.
Description of the procedure:
(a) The vial was weighed
(b) The vial was completely filled with water and hold for 30 min. at 20 °C under temperature control. Then the vial was weighed again
(c) The vial was emptied, cleaned and dried and filled with the melted sample, then weighed
GLP compliance:
yes
Type of method:
pycnometer method

Remarks:
mean value of two determinations

The determined density has to be regarded as an approximate value.

Conclusions:
A relative density of 1.333 (mean value of two determinations) to test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate was measured at 20 °C.
Executive summary:

With the test item phosphorothioyltris(oxybenzene-4,1-diylcarbamoyloxyethane-2,1-diyl) trisprop-2-enoate, the relative density was determined by the displacement method according to OECD 109.

A relative density of 1.333 (mean value of two determinations) was measured at 20 °C. The determined density has to be regarded as an approximate value.
