pKa = 3.9 (calculated)

Key value for chemical safety assessment

Additional information

The dissociation constant of the test item was not determinable by spectrophotometric method according to OECD 112 due to no significant differences within the UV spectra at pH=1.25 and pH=12.5. However, the dissociation constant was calculated by ACD pKa software (v4.5).
