Conclusions:
The water solubility of the substance at 20°C was determined to be 21.8 g/L using the flask method (in accordance with EC A.6, OECD 105 and OPPTS 830.7840 and in compliance with GLP). The pH of the water fraction after the test was 8.7. Based on the results, the test substance is considered to be very soluble (>10000 mg/L).

Description of key information

The water solubility of the substance

at 20°C was determined to be 21.8 g/L

using the flask method (in accordance

with EC A.6, OECD 105 and OPPTS 830.7840

and in compliance with GLP). The pH

of the water fraction after the test was 8.7.

Key value for chemical safety assessment
