Cas no 2628-16-2 (4-Acetoxystyrene)

4-Acetoxystyrene is a versatile monomer used primarily in polymer and materials science. Its key advantage lies in its reactive vinyl group and acetoxy functionality, enabling copolymerization with styrenics and other monomers to modify polymer properties. The acetoxy group can be hydrolyzed post-polymerization, offering a pathway to poly(4-hydroxystyrene), a precursor for photoresists and advanced coatings. This compound exhibits good thermal stability and solubility in common organic solvents, facilitating processing in industrial applications. Its utility in lithography, adhesives, and specialty polymers makes it valuable for high-performance material synthesis. Proper handling is required due to its potential sensitivity to polymerization initiators.

Comprehensive Guide to 4-Acetoxystyrene (CAS No. 2628-16-2): Properties, Applications, and Industry Insights

4-Acetoxystyrene (CAS No. 2628-16-2), also known as p-acetoxystyrene or vinyl phenyl acetate, is a versatile monomer widely used in polymer chemistry and specialty material synthesis. This compound features a reactive vinyl group and an acetoxy functional group, making it a valuable intermediate for creating high-performance polymers, coatings, and adhesives. Its molecular structure (C10H10O2) enables unique polymerization behaviors, aligning with modern demands for sustainable and functional materials.

In recent years, 4-Acetoxystyrene has gained attention due to its role in developing biodegradable polymers and photoresist materials for electronics. Researchers and manufacturers frequently search for "4-Acetoxystyrene synthesis," "CAS 2628-16-2 solubility," and "p-acetoxystyrene polymerization," reflecting its technical relevance. The compound’s compatibility with radical polymerization and copolymerization techniques further expands its utility in advanced material science.

From a commercial perspective, 4-Acetoxystyrene is critical in producing styrene-acrylate copolymers, which are essential for water-based paints and pressure-sensitive adhesives. Industry trends show growing interest in "eco-friendly monomers" and "low-VOC alternatives," where this compound’s derivates offer solutions. Its thermal stability (decomposing above 200°C) and solvent compatibility (e.g., with THF, acetone) make it suitable for industrial-scale applications.

Safety and handling of CAS No. 2628-16-2 follow standard laboratory protocols, with emphasis on proper ventilation and PPE. While not classified as hazardous under normal conditions, its storage recommendations (cool, dry, inert atmosphere) are frequently queried alongside "4-Acetoxystyrene shelf life." Regulatory databases like REACH and FDA provide guidelines for its use in specific applications, particularly in packaging materials.

Innovations in 4-Acetoxystyrene-based materials are driving patent filings, especially for UV-curable resins and nanocomposites. Recent studies highlight its potential in 3D printing resins, responding to searches like "photopolymerization monomers for additive manufacturing." As industries prioritize circular economy principles, the compound’s role in recyclable polymer designs is under active exploration.

For procurement specialists, key considerations include purity grades (technical vs. reagent) and suppliers’ adherence to ISO standards. Analytical methods such as GC-MS and HPLC are typically used for quality verification, addressing common queries like "how to test 4-Acetoxystyrene purity." Global market analyses project steady demand growth, particularly in Asia-Pacific regions, for electronics and automotive coating sectors.
