Decomposition product of Erythritol.

3,4-Dihydroxy-1-butene, also known as 3-butene-1,2-diol (BDdiol), is a metabolite of 1,3-butadiene. It forms the precursor for synthesizing different chiral building blocks. BDdiol can undergo oxidation to form hydroxymethylvinyl ketone (HMVK). 1,2-epoxy-3-butene (EB) on hydrolysis in the presence of epoxide hydrolases (EH) forms BDdiol.
