Aromatic methacrylate-based material likely containing a silica/siloxane component
Sample & Measurement Parameters
Identification Result
36%The FTIR spectrum most closely matches aromatic methacrylate-type compounds, with strong indications of ester, methacrylate, and aromatic ring vibrations, along with bands characteristic of silica or siloxane structures. The reference library comparison provided a low-confidence match to 3-(4-Chlorophenyl)-1-methoxy-1-methylurea, but the consensus of the top candidates and the direct literature evidence supports a broader classification as an aromatic ester/methacrylate material, possibly a composite containing an inorganic silica filler FTIR In-Depth Interpretation was not selected for this task, so this section shows the library-search result only and no deep AI interpretation was run.
Detailed interpretation
- Top library match: 3-(4-Chlorophenyl)-1-methoxy-1-methylurea #33549
- The nearest library match, 3-(4-Chlorophenyl)-1-methoxy-1-methylurea, had very low spectral similarity (0.000) and cannot be confirmed.
- The presence of Si-O bands, possibly from silica, does not correspond to the pure organic library candidates and may indicate an inorganic filler or contamination.
- No specific compound identity could be established; the assignment rests on functional group interpretation rather than a definitive match.
