The main component may be a methoxy- or methacrylate-containing material. The sample spectrum shows a strong carbonyl absorption at 1731 cm⁻¹ consistent with an ester or methacrylate moiety, a broad O–H stretch near 3456 cm⁻¹ indicative of hydroxyl or carboxylic acid, and C–O stretching at 1116 cm⁻¹ typical of ether or ester linkages. An absorption at 1536 cm⁻¹ could arise from C=C unsaturation often present in methacrylates. These features align with a functional-group direction dominated by oxygenated organics with methoxy/methacrylate character as indicated by the library, though no single library entry simultaneously accounts for all observed peaks. Confirmatory analysis by GC-MS or NMR is recommended to resolve the exact ester/alcohol structure
