Density
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 1994
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP guideline study with acceptable restrictions.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- yes
- Remarks:
- Measured temperature 22 ° C instead of 20 ° C.
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51757
- Deviations:
- no
- Principles of method if other than guideline:
- Approximately 0.7 mL of the liquid sample are filled into an U-shaped tube, which is able to oscillate. The change in the oscillation frequency due to changes in the mass of the oscillating tube is used to determine the density of the sample using calibration data.
- GLP compliance:
- yes
- Type of method:
- oscillating densitimeter
- Type:
- relative density
- Density:
- 1.02 other: g/mL
- Temp.:
- 22 °C
- Conclusions:
- The density of dimethyl propylphosphonate was determined as 1.0202 g/mL at 22 °C.
- Executive summary:
The density of dimethyl propylphosphonate was determined as 1.0202 g/mL at 22 °C.
Reference
Result (density at 22 °C):
Concentration 100 mg/mL = 1.0090 g/mL
Concentration 200 mg/mL = 1.0202 g/mL
Concentration 400 mg/mL = 1.0406 g/mL
Description of key information
The density of dimethyl propylphosphonate was determined as 1.0202 g/mL at 22 °C.
Key value for chemical safety assessment
- Relative density at 20C:
- 1.02
Additional information
Deviation: Density determined at 22 °C instead of 20 °C.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
