  • Applications

    Propanoic acid, 2-hydroxy-, 2-methyl-4-oxo-4H-pyran-3-yl ester (CAS 67860-02-0) is an ester of lactic acid linked to a 2-methyl-4-oxo-4H-pyran-3-yl group. In practice, it is considered a fragrance ingredient or aroma chemical, a potential precursor for the synthesis of more complex aroma compounds; it may be used in cosmetics and personal care formulations as an odor component or fragrance carrier; it can serve as a building block in organic synthesis for diverse specialty chemicals; and it may be evaluated as a specialty plasticizer or coating additive for polymers. These applications are typically explored in fragrance, flavor, cosmetics, and industrial formulation contexts, subject to local regulations.
