Description

3-Buten-2-One, 4-(Ethylamino)-3-Methyl-, (E)- (9Ci) is a specialized organic compound featuring an α,β-unsaturated ketone (enone) core functionalized with an ethylamino group, making it a valuable chiral building block and intermediate. This compound matters for its role in facilitating the synthesis of complex molecules, particularly in the development of active pharmaceutical ingredients (APIs) and advanced agrochemicals. It is primarily needed by research chemists and process development scientists in the pharmaceutical, agrochemical, and fine chemical industries for constructing nitrogen-containing heterocycles and other sophisticated target structures.

Application

• Pharmaceutical Intermediate: Key chiral synthon for the synthesis of novel drug candidates, particularly those targeting neurological and anti-infective pathways.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides that require specific stereochemistry for optimal activity.
• Fine Chemical Manufacturing: Serves as a versatile precursor for specialty chemicals, flavors, and fragrances requiring precise molecular architecture.
• Academic & Industrial Research: Employed in methodological studies and the development of new asymmetric synthesis and catalysis protocols.
• Material Science Precursor: Potential intermediate for functionalized polymers or organic electronic materials due to its conjugated system and reactive sites.
