• Top library match: cyclohexane-1,3,5-triol #25637

• Some direct‑evidence peak assignments conflict with a purely organic composition: 854 cm⁻¹ is attributed to fluorine [6], 937 cm⁻¹ to fructan [8], 1022 cm⁻¹ to Al–O–Si bridges [4], and 1092 cm⁻¹ to Si–O stretching [9], suggesting the literature sources may reference inorganic or hybrid materials that do not align with the methoxy/methacrylate direction.
• The library hit confidence is low (15 %), and the top candidate (cyclohexane‑1,3,5‑triol) differs significantly from the methoxy/methacrylate direction, leaving open the possibility of a mixed or hybrid organic/inorganic material.
• The simultaneous presence of aromatic, amide, and carboxylate signatures makes a definitive structural assignment impossible from FTIR alone.
• The direct‑evidence peak assignments introduce fluorine, Si–O, and Al–O–Si vibrations; if these are real sample components, they could indicate an inorganic filler or coating, but their relevance cannot be confirmed without additional data.

Recommended next steps: Verify the presence of inorganic components (silicon, aluminum, fluorine) by XRF or EDS to resolve the conflicting literature peak assignments. Obtain a Raman spectrum or perform thermogravimetric analysis to differentiate between ester, carboxylate, and amide functionalities. Compare the spectrum with a reference library of methacrylic copolymers and pigment‑binder mixtures to test the pigment mixture hypothesis raised by the related literature. If possible, perform solvent extraction or hydrolysis to identify the main organic backbone and search for a more specific library match.
