Results and discussion

Water solubility
Water solubility:
ca. 0.151 mg/L
Temp.:
25 °C
Remarks on result:
other: Relative St Dev 8.6%
Details on results:
Four aqueous solubility runs are summerized:
flow rate through saturator column (ml/min): 1, 2.5, 1, 2.5
total volume collected (ml): 5, 5, 10, 10
measured concentration in saturated solution (ppb): 147, 134, 160, 162 Mean: 151 St Dev: 8.6%
temperature: (25 ± 2)°C
Blank runs without the saturator column produced no measurable interferences.

Applicant's summary and conclusion

Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The aqueous solubility of MCS 1980 was determined to be 0.151 mg/l with a standard deviation of 0.13 mg/l.
Executive summary:

The aqueous solubility of MCS 1980 was measured by the saturator column technique according to an internal procedure. The mean measured concentration in saturated solution at ambient temperature was determined to be 0.151 mg/l with a standard deviation of 0.13 mg/l
