Results and discussion

Water solubility
Water solubility:
3.692 g/L
Temp.:
30 °C
pH:
ca. 3
Details on results:
A preliminary test indicated that the solubility of BMS 528233-01 in water was between approximately 2 and 5 g/L. Calibration data: the calibration line was established linearly. The temperature of the incubation bath over the period of the test was maintained at 20.1°C.
