Infrared spectrum comparison chart.
Analysis result: aromatic / methacrylate polymer with ether, hydroxyl, and unsaturated groups.
The FTIR spectrum suggests an aromatic/methacrylate-based material containing ether linkages, hydroxyl groups, unsaturated carbon–carbon bonds, alkyl chains, and carboxylate moieties. A definitive identification as a single pure compound is not supported because the expected strong ester carbonyl absorption (~1720 cm⁻¹) is absent, and the characteristic C–F stretching bands of the top library match are not observed. The most defensible direction is a methacrylate‑rich polymer resin or oligomer with aromatic character and oxygenated functionalities, consistent with the library consensus but remaining broad
