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

Conclusion

aromatic / methacrylate polymer with ether, hydroxyl, and unsaturated groups

Confiance globale

Conclusion

Library consensus points strongly to aromatic/methacrylate chemistry, with top entries including poly(ethylene glycol) methacrylate, siloxane‑containing materials, and methacrylate‑based polymers.
Multiple independent literature sources support the presence of hydroxyl, ether, and alkyl functionalities, all of which are compatible with a methacrylate‑rich polymer bearing polyethylene glycol or aliphatic ether segments.
The band at 3336 cm⁻¹ is attributed to O–H stretching of hydroxyl groups [2].

Evidence

2,2,3,3-Tetrafluoropropan-1-ol #65316

Limitations

Evidence that limits the conclusion

No bands characteristic of C–F stretching (1000–1400 cm⁻¹) are observed, making the top library hit (2,2,3,3‑tetrafluoropropan‑1‑ol) chemically unlikely.
The expected strong ester carbonyl absorption near 1720 cm⁻¹, a key marker of conventional methacrylate polymers, is absent from the set of prominent peaks, challenging a simple methacrylate homopolymer identification.
Without additional spectral data, the exact balance between aromatic, methacrylate, ether, and siloxane components remains undetermined.

Recommendation

Suggested next verification

Acquire the full FTIR spectrum over 4000–400 cm⁻¹, particularly the 1800–1650 cm⁻¹ (carbonyl) and 1400–600 cm⁻¹ (C–F, aromatic C–H, Si–O) regions, to confirm or rule out carbonyl, aromatic ring, and halogenated species.
Compare the spectrum with reference spectra of known methacrylate polymers, fluorinated alcohols, and siloxane‑containing copolymers to resolve the ambiguity.
If possible, perform complementary analysis (e.g., Raman spectroscopy, NMR, or XPS) to identify the presence of fluorine, silicon, or specific functional groups.
