In the realm of material science, protecting products from the detrimental effects of ultraviolet (UV) radiation is paramount. Degraded polymers, faded coatings, and compromised material integrity are common issues when materials are exposed to sunlight. This is where advanced UV absorbers play a critical role. One such highly effective compound is 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate, often identified by its CAS number 96478-09-0.

As a leading fine chemical manufacturer and supplier based in China, we are committed to providing high-quality materials that drive innovation. This specific methacrylate monomer stands out due to its dual functionality: it acts as a potent UV absorber and also possesses a polymerizable methacrylate group. This unique combination allows it to be chemically bonded into polymer chains, offering permanent and non-migrating UV protection, unlike conventional additives that can leach out over time. If you are looking to buy this specialized chemical for your formulation needs, understanding its properties is key.

The chemical structure of 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate features a benzotriazole moiety, renowned for its exceptional ability to absorb UV light. Upon absorbing a UV photon, the molecule undergoes an excited-state intramolecular proton transfer, efficiently dissipating the energy as heat. This mechanism is crucial for preventing photo-oxidation and photodegradation of the host material. With a melting point typically between 96-98°C, this compound presents itself as a stable white to yellow crystalline powder, making it manageable for industrial applications.

The molecular formula C18H17N3O3 and molecular weight of 323.35 g/mol are indicative of its complex yet highly functional design. Its primary application lies in enhancing the durability and performance of various materials. For instance, in the coatings industry, it can significantly improve the weatherability and color fastness of paints and varnishes exposed to prolonged sunlight. Manufacturers seeking to produce high-performance automotive, architectural, or industrial coatings will find this monomer invaluable.

Furthermore, its utility extends to polymer stabilization. By being incorporated into polymer matrices such as acrylics or polycarbonates, it shields them from UV-induced embrittlement and discoloration. This is particularly important for products intended for outdoor use, like plastic furniture, automotive parts, and construction materials. If you are a purchasing manager for a polymer manufacturing company, sourcing this UV absorber from a reliable supplier in China can offer a competitive price advantage without compromising on quality.

Beyond industrial applications, this benzotriazole methacrylate has also found promising uses in more specialized fields, such as dental materials and biomedical devices. Its ability to copolymerize into dental adhesive resins suggests potential for enhanced material stability and even antibacterial properties, which are highly sought after in modern dentistry. For researchers and product developers in the biomedical sector, its application in intraocular lenses to prevent UV-induced opacification is another compelling area.
