In the vast landscape of polymer science, extending the service life and maintaining the aesthetic and mechanical integrity of polymeric materials is a constant pursuit. A primary antagonist to polymer longevity is ultraviolet (UV) radiation, which initiates degradation pathways leading to embrittlement, discoloration, and loss of physical properties. To counter this, the chemical industry has developed sophisticated UV stabilizers, with reactive monomers like 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate (CAS 96478-09-0) offering superior solutions.

As a premier manufacturer and supplier of fine chemicals from China, we specialize in providing advanced monomers that empower material scientists and product developers. This particular benzotriazole-based methacrylate is highly valued for its dual role: it functions as an effective UV absorber and simultaneously acts as a reactive comonomer. This feature is critical because it allows the UV stabilizer to become an integral part of the polymer backbone through copolymerization. This covalent bonding prevents the migration and leaching of the additive, ensuring long-lasting and consistent UV protection throughout the material's lifespan.

The inherent mechanism of UV absorption in 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate is rooted in its benzotriazole structure. This moiety efficiently captures UV photons, particularly in the 300-400 nm range, and then dissipates this energy rapidly as heat via an excited-state intramolecular proton transfer. This process effectively shields the polymer from UV-induced damage. Typically supplied as a white to yellow crystalline powder with a melting point of 96-98°C, it's a practical choice for incorporation into various polymerization processes.

The chemical identity, represented by its molecular formula C18H17N3O3 and a molecular weight of 323.35 g/mol, underscores its complex yet highly functional design. Purchasing this monomer allows manufacturers to create polymers with significantly enhanced durability, resistance to weathering, and improved color stability. Its applications are widespread, ranging from high-performance plastics used in outdoor furniture, automotive exteriors, and construction materials, to protective coatings and even specialized applications like intraocular lenses where UV stability is critical.

For procurement professionals and R&D scientists, securing a reliable supply of high-purity 2-[3-(2H-Benzotriazol-2-yl)-4-hydroxyphenyl]ethyl Methacrylate is essential. As a leading manufacturer in China, we pride ourselves on consistent quality control and competitive pricing, making it an attractive option for businesses looking to source this advanced material. Its integration into polymer formulations can lead to products that not only perform better but also maintain their appearance and structural integrity under prolonged UV exposure.
