The FTIR spectrum is consistent with an aromatic or methyl‑containing organic material that also exhibits clear carbonyl and carboxylate signatures. A strong band at 1713 cm⁻¹ reveals carbonyl (C=O) stretching typical of esters, ketones, or carboxylic acids, while the peak at 1409 cm⁻¹ matches carboxylate symmetric stretching. Absorptions at 1018 and 1108 cm⁻¹ lie in the C–O stretching region and can originate from organic esters, polysaccharides, or phosphate groups. The library’s top match, 3‑chloropyridine, is not confirmed because the expected C–Cl vibrations are absent; the collective evidence points toward a mixed organic system with both carbonyl/carboxyl and C–O/phosphate character 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.
