Description of key information

Hex-3-yne-2,5-diol is miscible with water at room temperature (T = 23°C) and at T = 20.0°C ± 0.5°C in any ratio.

Key value for chemical safety assessment

Additional information

A GLP study was conducted in accordance with the OECD Guideline for the Testing of Chemicals 105 using the flask method.

The water solubility of substances with an expected high solubility is normally determined according to the flask method

described in OECD Guideline for the Testing of Chemieals 105. To apply this method, the preparation of a saturated

solution of test item in water is required. Since this is not possible for this test item, a homemade method described in

the External method EM/00408/01 from Competence Center Analytics, BASF SE (chapter 4: visual method) was applied to

investigate complete miscibility.

This study results that Hex-3 -yne-2,5 -diol is miscible with water at room temperature (T = 23°C) and at T = 20.0°C ± 0.5°C in any ratio.
