Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Study period:
12/01/1995- 25/07/1997
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
other: The study is considered to be a reliability 1 as it has been conducted according to OECD TG 105 using the column elution method and in compliance with GLP.
Qualifier:
according to
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Type of method:
column elution method
Key result
Water solubility:
2.68 mg/L
Temp.:
20 °C
pH:
> 6.59 - < 6.69
Details on results:
Calibration data show a slope of 8140.3, an intercept of -17441 and a correlation coefficient of 0.99938 showing the detector response to be linear in the concentration range employed.

Water solubility ranges from 2.4704 x 10^-3 to 2.6543 x 10^-3 g/l (mean 2.5485 x 10^-3 g/l) for column A and 2.6543 x 10^-3 g/l to 2.9207 x 10"-3 g/l (mean 2.8159 x 10^-3 g/l) for column B, overall mean water solubility is 2.6822 x 10^-3 g/l. The pH of test solutions in column A was 6.59 and column B 6.69. The pH of the blank solution was 4.78. No observable peak was seen in any of the blank solutions at any of the characteristic retention times of OTNE indicating that the method is free from interference.

The mean percentage recovery was 99.5 (mean of 98.2%, 97.9% and 102.3%).
Conclusions:
Interpretation of results (migrated information): slightly soluble (0.1-100 mg/L)
The water solubility of OTNE was determined to be 2.68 mg/l at 20°C using OECD TG 105 (Water solubility) using the column elution method in compliance with GLP.
Executive summary:

The water solubility of OTNE was determined to be 2.68 mg/l at 20°C using OECD TG 105 (Water solubility) using the column elution method.
