Description

3-Butenamide CAS NO 432491-67-3 is a versatile, unsaturated amide compound that serves as a valuable building block in advanced organic synthesis. Its terminal alkene and amide functionalities make it a critical intermediate for constructing complex molecular architectures. This high-purity intermediate is essential for research and development in the pharmaceutical, agrochemical, and specialty polymer industries, where it is used to introduce reactive handles for further chemical elaboration.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs) and novel drug candidates, particularly those requiring an acrylamide or vinylogous amide moiety.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators that incorporate the butenamide structure.
• Polymer Chemistry: Acts as a monomer or co-monomer for creating specialty polymers with tailored properties, such as polyacrylamides or functionalized resins.
• Chemical Research: Serves as a fundamental reagent in organic synthesis for Michael addition reactions, cycloadditions, and as a precursor to other functionalized amides and amines.
• Material Science: Utilized in the development of advanced materials, including coatings, adhesives, and composites that benefit from its reactive double bond.
• Bioconjugation: Potential use in bioconjugation chemistry for labeling proteins or other biomolecules due to its reactive alkene group.
