Identification Result
69%The sample is consistent with an aromatic anhydride, most probably a phenyl-substituted maleic anhydride derivative. The spectrum exhibits characteristic anhydride C=O stretches, mono-substituted benzene ring vibrations, and aromatic and aliphatic C-H modes 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-Phenylfuran-2,5-dione #11733
- The library similarity is low (0.622), indicating that the match is not clear-cut; the sample could be a derivative, isomer, or mixture containing the proposed anhydride structure.
- Broad O-H stretching bands around 3726 cm⁻¹ suggest the presence of moisture or hydroxyl groups, which could arise from partial hydrolysis of the anhydride; this does not contradict the assignment but adds uncertainty about the sample's integrity.
