1,2-Butanediol Usage And Synthesis
Chemical Propertiesclear colorless liquid
Uses1,2-Butanediol was used in the synthesis of (R)-2-hydroxybutyric acid.
DefinitionChEBI: A butanediol in which the two hydroxy groups are located at positions 1 and 2.
Flammability and ExplosibilityNon flammable
Safety ProfileModerately toxic by ingestion. Combustible when exposed to heat or flame. To fight fire, use alcohol foam. When heated to decomposition it emits acrid and irritating fumes.
