Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

water solubility
Type of information:
Adequacy of study:
key study
Study period:
2017 April 04
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
results derived from a valid (Q)SAR model and falling into its applicability domain, with limited documentation / justification
Justification for type of information:
Estimated data are obtained from a reliable (Q)SAR program developed and validated by the United States Environmental Protection Agency (U.S. EPA). This program is included in the OECD (Q)SAR Toolbox for use in filling REACH data gaps.
no guideline followed
Principles of method if other than guideline:
Estimated data are obtained from a reliable (Q)SAR program based on fragment analysis (U.S. EPA EPI-Suite WSKOW v1.42).
GLP compliance:
Type of method:
other: (Q)SAR
Key result
Water solubility:
0.01 mg/L
Conc. based on:
test mat.
25 °C
Remarks on result:
other: assume neutral pH

Log Kow (estimated) : 6.30 

Log Kow (experimental): not available from database

Log Kow used by Water solubility estimates: 6.30


Equation Used to Make Water Sol estimate:

  Log S (mol/L) = 0.796 - 0.854 log Kow - 0.00728 MW + Correction

    (used when Melting Point NOT available)


   Correction(s):     Value

    No Applicable Correction Factors


  Log Water Solubility (in moles/L) : -7.602

  Water Solubility at 25 deg C (mg/L): 0.01038


The substance is considered insoluble in water, as the quantitative estimate is 0.01038 mg/L at 25 ˚C,according to U.S. EPA EPI-Suite WKSOW v1.42 of EPI-Suite v4.11.
