Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Reference
Endpoint:
water solubility
Type of information:
experimental study
Adequacy of study:
key study
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to guideline
Guideline:
OECD Guideline 105 (Water Solubility)
Deviations:
yes
Remarks:
Due to the UVCB nature of the substance, the OECD guideline is slightly modified to account for that. The modifications are outlined in the field “principles of method if other than guideline”
Qualifier:
according to guideline
Guideline:
EU Method A.6 (Water Solubility)
Deviations:
no
Principles of method if other than guideline:
Deviation from Guideline OECD 105:
OECD 105 allows to determine the water solubility of pure compounds. In a mixture or multi-constituent substance, every constituent has its own solubility which may differ from the solubility of the others. The solubility of a mixture in total can therefore only be estimated from the point, a significant amount of the sample is no longer soluble. Due to the fact that usually no standard compounds are available for the mixture constituents, the dissolved amount of the sample has to be determined using a suitable sum-parameter method (e.g. total organic carbon) related to the total content of the sum-parameter in the sample (e.g. in this case carbon).
GLP compliance:
yes (incl. QA statement)
Type of method:
flask method
Water solubility:
ca. 4 g/L
Temp.:
20 °C
pH:
5.4 - 6.1
Conclusions:
The water solubility of the test item in demineralized water is estimated to be approx. 4 g/L at 20 °C and pH 5.4 - 6.1. It classifies as: soluble (1000-10000 mg/L)
Executive summary:

The water solubility of the test item in demineralized water is estimated to be approx. 4 g/L at 20 °C and pH 5.4 - 6.1. The test substance contains approx. 10 % insoluble parts in demineralized water. (CURRENTA, 2009).
