Conclusions:
The melting point determination of 4,4'-bis(2-methoxystyryl)-1,1'-biphenyl (CAS No. 40470-68-6) was done following OECD Guideline 102 and according to the metal block capillary method. Based on the test results, the melting range could be confirmed: 219.2°C ~ 220.0°C at 101325 Pa.
Executive summary:

The melting point determination of 4,4'-bis(2-methoxystyryl)-1,1'-biphenyl (CAS No. 40470-68-6) was done following OECD Guideline 102 and according to the metal block capillary method. Based on the test results, the melting range could be confirmed: 219.2°C ~ 220.0°C at 101325 Pa.

Description of key information

The melting point determination of 4,4’-bis(2-methoxystyryl)-1,1’-biphenyl (CAS No. 40470-68-6) was determined according to “Capillary tube in a metal block - Apparatus with photocell detection” in OECD 102 - “Melting Point / Melting Range. Based on the test results, the melting range could be confirmed: 219.2°C ~ 220.0°C

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
220 °C

Additional information

The melting point determination of 4,4’-bis(2-methoxystyryl)-1,1’-biphenyl (CAS No. 40470-68-6) was determined according to “Capillary tube in a metal block - Apparatus with photocell detection” in OECD 102 - “Melting Point / Melting Range. Based on the test results, the melting range could be confirmed: 219.2°C ~ 220.0°C

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of melting point range as 219.2°C ~ 220.0°C  thus considered as key study for the chemical safety assessment.
