4-Ethenylphenol Acetate丨CAS 2628-16-2

4-Ethenylphenol acetate is an organic intermediate widely used in polymer chemistry, resin modification, and fine chemical synthesis. Its structure, featuring both an acetylated phenolic moiety and a reactive ethenyl group, makes it valuable in the preparation of specialty polymers, copolymers, and crosslinked materials. It is often incorporated into resin formulations to introduce improved thermal stability, rigidity, or specific aromatic characteristics. In organic synthesis, it serves as a protected form of vinylphenol, allowing controlled deprotection and functionalization steps in multi-stage synthetic pathways. It is also used in the development of additives, stabilizers, and surface-active agents where aromatic functionality and controlled reactivity are required. In research environments, the molecule is applied in studies of radical polymerization behavior, monomer reactivity ratios, and structure–property relationships in polymeric materials.

4-Ethenylphenol acetate offers several benefits that enhance its utility in synthetic and materials applications. The acetylated phenolic group provides increased stability and reduces premature polymerization or oxidation, improving storage and handling safety. Its ethenyl functionality enables predictable and efficient participation in polymerization reactions, giving researchers and formulators precise control over material structure and performance. The compound's dual reactivity-vinyl polymerization potential and acetyl-protected phenol chemistry-allows flexible integration into diverse synthetic sequences without unwanted side reactions. This versatility makes it useful for designing materials with enhanced thermal, mechanical, or chemical resistance. Additionally, its relatively straightforward incorporation into copolymers supports the creation of customized materials tailored to specific industrial or research needs.
