Description

Benzyl methacrylate (CAS 2495-37-6) is a high-purity monomer with the molecular formula C₁₁H₁₂O₂ and IUPAC name benzyl 2-methylprop-2-enoate. This clear, colorless to pale yellow liquid is a versatile acrylate ester widely used in polymer chemistry and material science. With a characteristic mild odor, it offers excellent reactivity due to its methacrylic functional group and benzyl ester moiety. Our product is rigorously tested to ensure optimal purity (>98%) and stability, making it ideal for controlled polymerization reactions. Suitable for free-radical, anionic, and group transfer polymerization techniques. Packaged under inert gas to prevent premature polymerization. Store in a cool, dry place away from light and oxidizing agents.

Key Specifications: Molecular Weight: 176.21 g/mol, Density: 1.04 g/cm³ at 25°C, Boiling Point: 235°C, Flash Point: 107°C. Hazard Codes: Xi (Irritant).

Application

Benzyl methacrylate serves as a key monomer for synthesizing specialty polymers with tailored properties. It’s particularly valuable for creating transparent, high-refractive-index materials used in optical applications. The benzyl group imparts enhanced solubility and flexibility to resulting polymers. Researchers utilize it to develop advanced copolymers for coatings, adhesives, and photoresists. Its reactivity also makes it suitable for grafting reactions and polymer modification studies.
