Description

3-Buten-2-One, 4-(Methoxymethoxy)-3-Methyl-, (3E)- (9Ci) is a specialized, high-purity chemical intermediate featuring a reactive α,β-unsaturated ketone moiety protected by a methoxymethyl (MOM) ether group. This compound matters for its role as a versatile building block in advanced organic synthesis, enabling the controlled introduction of functionalized butenone units into complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing active pharmaceutical ingredients (APIs), novel crop protection agents, and sophisticated fragrance components.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of complex drug molecules, particularly those requiring stereoselective Michael addition reactions.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where the protected carbonyl functionality is crucial for selective reactivity.
• Fine Chemical Manufacturing: Serves as a precursor for specialty chemicals, including flavors, fragrances, and advanced material precursors.
• Academic & Industrial Research: A valuable reagent for methodological development in organic chemistry, including studies on conjugate additions and protective group chemistry.
• Material Science: Potential monomer or cross-linking agent in the development of specialized polymers with tailored properties.
