Identification Result
21%The infrared spectrum is consistent with an oxygenated organic material containing aromatic rings, a carbonyl group (ester or ketone), and probable sulfate or amide moieties. The nearest library match is 6-hydroxy-2-phenylchromen-4-one, but the low similarity (15%) prevents a definitive structural assignment, and the evidence points toward a ring‑ and sulfate‑bearing organic system 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.
