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.

Additional information

The water solubility of the substance UMA121 (EC-No. 923 -201 -3) was determined on the basis of OECD Guideline 105 and EU Method A.6. The flask method was used. No preliminary test was performed. Two concentrations, differing more than 15% (100 mg/L and 1000 mg/L) were tested. Because of the low water solubility and the agreement of the values obtained with both concentrations, no more tests were performed and the mean of the results has been reported.
