Acetoin, tseem hu ua 3-hydroxybutanone los yog acetyl methyl carbinol, nrog cov mis mos molecular yog C4H8O2, yog xim tsis muaj xim lossis daj daj mus rau ntsuab daj kua nrog qab ntxiag, buttery tsw. Acetoin yog chiral molecule. Daim ntawv tsim los ntawm cov kab mob yog (R)-acetoin. 3-Hydroxy-2-butanone yog cov tshuaj siv hauv cov khoom noj khoom haus thiab cov tshuaj tsw qab. Nws ua raws li qhov nruab nrab ntawm butanediol voj voog hauv cov kab mob. Nws yog siv los ua tus neeg nqa khoom aroma hauv kev npaj cov khoom qab zib thiab cov essences.
