- Specific details on test material used for the study:
- Lot No. 180705
Purity: 99.08%
Appearance: White crystal
Molecular Weight: 693.57 g/mol
Molecular Formula: C36H30N3O6P3
Storage condition: Room temperature - Analytical method:
- high-performance liquid chromatography
- Key result
- Type:
- log Pow
- Partition coefficient:
- 3.26
- Temp.:
- 25 °C
- pH:
- ca. 7
- Conclusions:
- Octanol/water partition coefficient of Phenoxycycloposphazene was 3.26±0.04. And this value of Log Pow is greater than 3. Thus, the test substance could be classfied as a high bio-concentrative chemical substance in the aquatic environment.
- Executive summary:
The results of Octanol/water partition coefficient of Phenoxycycloposphazene were as follows:
(1) The recoveries of the test substance Phenoxycycloposphazene, were 104.73±3.17% in 1 -octanol phase and 99.67±0.31% in water phase, respectively.
(2) The values of log Pow treated three different volume ratios of test substance solution were calculated to be 3.25±0.03, 3.22±0.01 and 3.30±0.06, respectively.
As a result, Octanol/water partition coefficient of Phenoxycycloposphazene was 3.26±0.04. And this value of Log Pow is greater than 3. Thus, the test substance could be classfied as a high bio-concentrative chemical substance in the aquatic environment.
