Appearance / physical state / colour
Administrative data
- Endpoint:
- appearance / physical state / colour
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 3 Nov 2017 to 6 Nov 2017
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: see Remarks
- Remarks:
- The appearance of the test item is described in a reliable study report on the physical-chemical properties of the substance. Since no guideline was followed and no details on the methods are given, the description is considered as reliable with restrictions.
Cross-reference
- Reason / purpose for cross-reference:
- reference to same study
Reference
- Endpoint:
- relative density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 3 Nov - 6 Nov 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.3 (Relative Density)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: "European Pharmacopoeia 9.0-5.11 Characters section in monographs - Solubility"
- Deviations:
- no
- GLP compliance:
- yes
- Type of method:
- pycnometer method
- Type:
- relative density
- Density:
- 1.427 other: no units
- Temp.:
- 20 °C
Results
Relative density at 20 °C was determined in duplicate as 1.441 and 1.413. The average result is 1.427.
Conclusions
Since the test sample proved to be soluble in water, the relative density determination was carried out in xylene. The relative density of "2MAOK-PW" at 20 °C proved to be 1.427.
