Description of key information

The determination of the pKa of hex-3-yne-2,5-diol is technical not feasible.

Key value for chemical safety assessment

Additional information

The test item was titrated with 0.1 mol/1 hydrochloric acid and 0.1 mol/1 NaOH. The titration graphs obtained of the test item

show no inflection points. The determination of the dissociation constant of an aqueous preparation of the test item was not possible.
