- Name: Pentaerythritol tetrabenzoate
Appearance: off-white solid
Composition: Pentaerythritol tetrabenzoate >96%
CAS No.: 4196-86-5
EINECS-No.: 224-079-8
Molecular formula: C33H28O8
Molecular weight: 552.576 g/mol
Purity: >96%
Homogeneity: homogeneous
Expiry date: Nov. 2018
Storage: Room Temperature (20 ± 5°C) - Key result
- Type:
- relative density
- Density:
- > 1.205 - < 1.206 g/cm³
- Temp.:
- 20 °C
- Conclusions:
- The density of the test item Pentaerythritol tetrabenzoate was calculated as 1.2058 ± 0.0005 g/cm3 at 20.0 ± 0.2 °C.
- Executive summary:
The density of Pentaerythritol tetrabenzoate was measured using the pycnometer method according to OECD 109 resp. EU A.3.
A density of 1.2058 ± 0.0005 g/cm3 at 20.0 ± 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 0.0024 g/cm3, showing good correlation of the two determinations.
