Description of key information

The water solubility of TS-ED 532 was estimated to  < 0.33 mg/l  at 20 ºC using the flask method. Using LC/MS, the water solubility was found to be  in the range of 0.06 - 0.09 mg/l. Overall, the water solubility of TS-ED 532 is found to be approximately 0.07 mg/l. 

Key value for chemical safety assessment

Water solubility:
0.07 mg/L
at the temperature of:
20 °C

Additional information

The water solubility of TS-ED 532 was determined using the flask method according to OECD and EC guidelines to less than 0.33 mg/l at 20 ºC ± 0.5 ºC. The solubility was derived from the lowest calibration point and the dilution factor.

Using an LC-MS method for analysis of aqueous solutions of TS-ED 532, the water solubility was found to be in the range of 0.06 - 0.09 mg/l. At concentrations above 0.09 mg/l, the analytical results indicate formation of an inhomogeneous system due to oversaturation (formation of micelles or other macro-structures).
