Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

- Endpoint:
- density, other
- Remarks:
- density
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Justification for type of information:
- Experimental result performed using standard methods of analysis
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 109 (Density of Liquids and Solids)
- Principles of method if other than guideline:
- The density can be determined according to “Pycnometer (liquids and solids)” in OECD Guidelines for the Testing of chemicals 109 - “Density of Liquids and Solids”. The density of the sample can be calculated based on these values - the mass of the pycnometer filled with hexane, the mass of the pycnometer with the sample added in it and filled with hexane followed, and the mass of the sample added in the pycnometer.
- GLP compliance:
- yes
- Type of method:
- pycnometer method
- Specific details on test material used for the study:
- - Name of test material: 4,4'-bis(2-methoxystyryl)-1,1'-biphenyl
- IUPAC name: 1-[(E)-2-(2-methoxyphenyl)ethenyl]-4-{4-[(E)-2-(2-methoxyphenyl)ethenyl]phenyl}benzene
- Molecular formula: C30H26O2
- Molecular weight: 418.53 g/mol
- Smiles notation: COC1=CC=CC=C1/C=C/C2=CC=C(C3=CC=C(/C=C/C4=CC=CC=C4OC)C=C3)C=C2
- InChl: 1S/C30H26O2/c1-31-29-9-5-3-7-27(29)21-15-23-11-17-25(18-12-23)26-19-13-24(14-20-26)16-22-28-8-4-6-10-30(28)32-2/h3-22H,1-2H3/b21-15+,22-16+

- density
- Density:
- ca. 1 179.5 kg/m³
- Temp.:
- 20 °C
- Conclusions:
- Based on the determination results, the sample density is 1.1795 g/cm3 = 1179.5 kg/m3 20 ºC.
- Executive summary:
In this guideline (OECD 109) study, the density of the test substance (EC 254-935-6) was determined to be 1179.5 kg/m3 at 20 ºC. Relative density (specific gravity) 1.1795.
Reference
