    Ethyl 5-oxohexanoate CAS 13984-57-1

    Ethyl 5-oxohexanoate, also known as ethyl 4-acetylbutyrate, is an aliphatic keto ester used as an organic synthesis intermediate in fine chemical and process chemistry applications. With both ester and ketone functional groups present in a single molecule (CAS 13984-57-1), it serves as a versatile precursor for condensation, cyclization, and functional group transformation reactions where controlled carbonyl reactivity is required. Industrial availability includes competitive factory pricing, support for customized specifications, and complete documentation such as MSDS, TDS, COA, enabling stable bulk supply for standardized industrial use.
