Solutions/mixtures
Blank: The Diluent was injected as blank sample.
Diluent: HPLC water and methanol was mixed in 45:55 (V/V) ratio.
t0 Solution: Approx. 100 mg Urea was weighted with 0.01 mg precision into 10 mL volumetric flask and filled up with Diluent. The solution was mixed well by hand. The concentrations of the urea was approx. 10 mg/mL.
Stock Solution of Reference Standards: Individual stock solutions were prepared from the selected reference standards. Approx. 10 mg reference compounds were weighted with 0.01 mg precision into 10 mL
volumetric flask and filled up with Diluent. The solution was mixed well by hand. The concentrations of the reference substances were approx. 1 mg/mL (cStock).
Reference Solutions: Reference Solutions (one reference standard per solution) was prepared from the Stock Solutions of Reference Standards to identify the compounds in the Reference Mixture. Calculated volume from the stock solutions (VStock) was pipetted into 10 mL volumetric flask (VMix) and filled up to volume with Diluent (cRefSt.).
Reference Mixture-1 and 2: Reference Mixture-1 (containing five and two reference standards in one solution, respectively) was prepared from the Stock Solutions of Reference Standards. Calculated volume from the stock solutions (VStock) was pipetted into 10 mL volumetric flask (VMix) and filled up to volume with Diluent. The concentrations of the reference standards in the Reference Mixture called cRefSt. in the tables below.
Stock Solution of Test Item: Approx. 10 mg test item was accurately weighted by analytical balance into 10 mL volumetric flask and filled up with Diluent and mixed well by hand.
Test Item Solution: 100 µL Stock Solution of Test Item was pipetted into 10 mL volumetric flask, filled up to volume with Diluent and mixed well by hand.
Determination of dead-time: Urea was injected for the determination of dead-time.
Calibration: The reference compounds in the Reference Mixture-1 and Reference Mixture-2 were identified based on the retention times measured in the Reference Solution. The known log Koc values were figured as a function of calculated log k and linear calibration curve was fitted.
The log Koc of the test item was determined using this calibration curve. - Analytical monitoring:
- not required
- Key result
- Type:
- log Koc
- Value:
- 3.26 dimensionless
- Temp.:
- 55 °C
- Matrix:

- Remarks on result:
- other: mean value (n = 3)
- Details on results (HPLC method):
- Urea was injected for the determination of dead-time. The reference compounds in the Reference Mixture-1 and Reference Mixture-2 were identified based on the retention times measured in the Reference Solutions. The known logKOC values were figured as a function of calculated log k and linear calibration curve was fitted. The test item was detected at 1.62 min retention time. The logKOC of the Azuril is estimated to be 3.26.
- Validity criteria fulfilled:
- yes
- Conclusions:
- The log Koc of the Azuril is estimated to be 3.26.
- Executive summary:
The log Koc of Azuril was determined using HPLC according to OECD TG 121. The Log Koc of Azuril was determined to be 3.26.
