- Principles of method if other than guideline:
- The Water Solubility Program (WATERNT) estimates the water solubility of organic compounds at 25oC. The WATERNT program and estimation methodology were developed at Syracuse Research Corporation for the US Environmental Protection Agency. The estimation methodology is based upon a "fragment constant" method very similar to the method of the KOWWIN Program which estimates octanol-water partition coefficients.
WATERNT automatically retrieves experimental water solubility values from a database containing more than 6200 organic compounds with measured values. When a SMILES structure matches a database structure (via an exact atom-to-atom connection match), the experimental water solubility value is retrieved and shown in the Results Window. - GLP compliance:

The calibration curve fits over the whole range from 0.07 to 6.5 mg/L with r²=1.000. Due to this wide working range, quadratic fit was used.
In course of the recovery experiment, an average rate of 110 % was determined.
No data given for pH.
The solubility of the test substance is less than the detection limit of GC-FID, which is stated to be 0.3 µg/mL (i.e. 0.3 mg/L).

Description of key information
Based on read-across to closely related structural analogues and QSAR estimation, the substance is considered to be insoluble in water.
Key value for chemical safety assessment
- Water solubility:
- 0 mg/L
- at the temperature of:
- 25 °C
Additional information
Based on structural features, the water solubility of the substance at 25 degr C was calculated to be < 1.1x10-5 mg/L using EPISuite 4.11 (estimation with WATERNT Program (v1.01)). Closely related structural analogues are slightly soluble or insoluble in water: CAS 11138-60-6 has a water solubility of 0.3 mg/L and CAS 78-16-0 has a water solubility of 0.05 mg/L (EU Method A.6.).
The substance is therefore considered to be insoluble in water.
A report justifying the read-across approach is included in IUCLID Chapter 13.
