Description

2-Phenoxyethyl acrylate (CAS No. 48145-04-6) is a high-purity, monofunctional acrylate ester with the molecular formula C₁₁H₁₂O₃. This versatile monomer is widely used in polymer chemistry and material science due to its reactive acrylate group and phenoxyethyl moiety, which enhance flexibility and adhesion properties in polymeric systems. It is a clear, colorless to pale yellow liquid with a characteristic mild odor, and it is soluble in common organic solvents such as ethanol, acetone, and ethyl acetate. Ideal for UV-curing applications, adhesives, coatings, and inks, this compound offers excellent crosslinking efficiency and low volatility. Proper storage under inert atmosphere and refrigeration is recommended to maintain stability and prevent premature polymerization.
