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.
