Key value for chemical safety assessment

Additional information

In consequence of the very low water solubility and the fact that an analytical method could not be developed to meet this low quantitation limit, an experimental determination of the dissociation constant is not possible.

A calculation using ACD/Labs, Software V11.02 (© 1994-2020 ACD/Labs) stated in SciFinder (Copyright © 2020 American Chemical Society. All Rights Reserved.) the following results:

pKa1= -1.00±0.45 at 25°C

pKa2= 2.09±0.20 at 25°C
