  • Applications

    2,3-Butanediol monoacetate (CAS 56255-48-2) is primarily used as an intermediate in organic synthesis, particularly as a chiral building block for pharmaceutical and agrochemical products; it may also serve as a solvent or co-solvent in industrial manufacturing and in coatings or adhesive formulations; it can act as a plasticizer or processing aid in polymer and coating applications; it can be used as a fragrance ingredient or odorant/fixative in perfumery and consumer care products; and it serves as a precursor to other acetylated derivatives in synthetic routes.
