Description

Isodecyl Methacrylate (CAS 29964-84-9) is a high-purity, monofunctional methacrylate ester with the molecular formula C₁₄H₂₆O₂. This clear, colorless liquid is characterized by its low volatility, excellent adhesion, and hydrophobic properties, making it a versatile monomer for advanced polymer formulations. Its IUPAC name, 8-methylnonyl 2-methylprop-2-enoate, reflects its branched alkyl chain structure, which enhances solubility and flexibility in copolymer systems. Isodecyl Methacrylate is widely used in UV-curable coatings, adhesives, and specialty resins due to its low viscosity and superior reactivity. Packaged under inert gas to ensure stability, this product is ideal for researchers and industrial scientists seeking consistent performance in radical polymerization applications.
