Description of key information

SPARC estimates pKa values of ca. 10.5 and ca. 10.7 at 25 °C for the first and second ionisable hydrogen atoms.

Key value for chemical safety assessment

pKa at 20°C:
10.5

Additional information

The acid dissociation constants (pKa) of the substance were estimated using the SPARC Performs Automated Reasoning in Chemistry (SPARC) program, October 2011 release w4.6.1691-s4.6.1687.

The substance contains two ionisable hydroxyl groups. The acid dissociation constants (pKa) of the substance were estimated to be ca. 10.5 (pKa 1) and ca. 10.7 (pKa 2).
