Link to relevant study record(s)
- Endpoint:
- flammable liquids: obsolete as covered by section 'Flash point'
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance is a liquid
- Principles of method if other than guideline:
- Expert Statement
- Interpretation of results:
- not classified based on GHS criteria
- Conclusions:
- (S)-1,3,4-trihydroxybutan-2-one does not contain groups that might lead to evolution of highly flammable gases in dangerous quantities.
Furthermore, no metals, transition metals, boron or silicon are present. Therefore, it can be concluded that the test substance is incapable of developing a dangerous amount of (flammable) gas in contact with air, damp air or water.
Moreover, during the addition of a small quantity of the test substance to double distilled water, it was observed that no spontaneous ignition took place and no evolution of gas occurred and (S)-1,3,4-trihydroxybutan-2-one is known to be water soluble. - Executive summary:

Description of key information
(S)-1,3,4-trihydroxybutan-2-one is not pyrophoric and not flammable in contact with water.
No flash point was observed up to 122°C and 121°C, in test 1 and 2 respectively. Both tests were terminated (at a temperature of 122°C and 121°C, respectively) because the test substance boiled out of the test cup. After the test, the test substance appeared to be a light brown liquid.
