Key result
Water solubility:
ca. 76 g/L
Conc. based on:
test mat.
Incubation duration:
ca. 3 d
Temp.:
20 °C
pH:
2.1
Details on results:
The detector calibration was found to be linear over the range 0 to 100 mg/L with a regression coefficient of 0.9997.
It shows a measured solubility of 75.9 ± 1.7 g/L.
An acceptable mean recovery of approximately 101% of Triazolone from fortified samples was achieved. Table 4 shows the recovery data.

Conclusions:
The water solubility of Triazolone was determined to be 76g/L at 20°C.
Executive summary:

A study was performed to determine some physicochemical properties of the test item, Triazolone. The methods followed are amongst those described in Council Regulation (EC) No. 440/2008 and the OECD Guidelines for the Testing of Chemicals. The physicochemical properties which have been determined in this study are detailed below, together with the result obtained for each test.
