guideline study
Qualifier:
according to guideline
Guideline:

Type of method:
flask method
Key result
Water solubility:
< 0.03 mg/L
Conc. based on:
test mat.
Temp.:
20 °C
pH:
ca. 7.1

mean value of 2 determinations

Conclusions:
The water solubility of the test material was determined to be <0.03 mg/l under the conditions of the test.
Executive summary:

Because the target analyze was undetected in each centrifugated solution, so it can be confirmed that the water solubility of 4,4’-bis(2-methoxystyryl)-1,1’-biphenyl (EC: 254-935-6) is less than LODe of the HPLC method.

LODe has been determined as 0.03 mg/mL and pH value of each centrifugated solution is 7.1, so Water Solubility is “＜0.03 mg/L (20ºC, pH7.1)”

Description of key information

Study carried out according to guideline.

Key value for chemical safety assessment

at the temperature of:
20 °C

Additional information

The determination was conducted using flask method at pH 7.1.

LODe has been determined as 0.03 mg/mL and pH value of each centrifugated solution is 7.1, so Water Solubility is “＜0.03 mg/L (20ºC, pH7.1)”
