Results and discussion
Partition coefficient
- Key result
- Type:
- log Pow
- Partition coefficient:
- -0.27
- Temp.:
- 22.5 °C
- pH:
- 7
- Details on results:
- The determined log POW value of 5-(Hydroxymethyl)furfural (CAS no. 58-61-7) at pH 7.0 and 22 to 23 °C is -0.27 with a standard deviation of ±0.01.
The validity criterion as specified in section 5.2 was met, because the determined log POW values were within ±0.3 units from the mean. Furthermore, the test was performed at a temperature in the range of 20 to 25 °C, kept constant at ±1 °C as given in the guideline.
Any other information on results incl. tables
- Goodness of fit: 1.0000 (R2 of the linear calibration regression)
- Repeatability: 0.3% (Relative Standard Deviation of the ten measurements)
- Accuracy: 97% (mean of the ten measurements relative to the expected value)
- Limit of quantification (LOQ) for 1-octanol phase as determined in the present study: 46.8 mg/l, based on the lowest standard solution measured (0.0780 mg/l) and including a sample preparation factor of 600.
- Limit of quantification (LOQ) for aqueous phase as determined in the present study: 0.104 mg/l, based on the lowest standard solution measured (0.0780 mg/l) and including a sample preparation factor of 1.333.
Validation parameters:
A validation was conducted in compliance with GLP during this study (calibration series followed by ten injections of a control standard at a concentration of 7.10 mg/l). The following validation parameters were derived:
Concentrations of the two phases, mass-balances and log Pow determinations

Applicant's summary and conclusion
- Conclusions:
- The determined log POW value of 5-(Hydroxymethyl)furfural at pH 7.0 and 22 to 23 °C is ¿0.27 with a standard deviation of ±0.01.
- Executive summary:
The log POW of the test item 5-(Hydroxymethyl)furfural (CAS no. 67-47-0) was determined according to the OECD guideline 107.
Phosphate buffer at pH 7.0, 1-octanol and the test item were equilibrated in test vessels by shaking, applying three different volume ratios of the two solvents. Subsequently, the test item concentrations were determined in both solvent phases.
The determined log POW values were in the range of ¿0.27 to ¿0.28 for all three volume ratios and all replicates. For each replicate, the mass balance calculation showed that the experiment was reliably conducted, as the recovery rates ranged from 99% to 101%.
The determined log POW value of 5-(Hydroxymethyl)furfural at pH 7.0 and 22 to 23 °C is ¿0.27 with a standard deviation of ±0.01.
The validity criterion was fulfilled.
