应用
4-Hydroxy-2-butanone is used in the preparation of fused benzazepine molecules as selective D3 receptor antagonists with pharmaceutical activity. It is also used in the preparation of verrucarin and mevalonic acid lactone. Further, it is used to prepare 3-buten-2-one through dehydration over an anatase titanium dioxide catalyst. It is also employed in the preparation of 4-methyl-5-hydroxymethylthiazole, (?±)-lineatin and beta-hydroxylactones.

备注
Incompatible with strong oxidizing agents.
