• Top library match: N-ethyl-3-phenyl-N-(3-phenylpropyl)propan-1-amine; 2-hydroxypropane-1,2,3-tricarboxylic acid #236

• All reported library similarities are 0.000, S-O the retrieved top candidate is not a meaningful spectral match.
• No supporting groups were reported for the top candidates, limiting confidence in any narrow library-based assignment.
• The observed spectrum does not provide clear, sample-specific support for the full mixed salt/amine-acid identity of the top library entry.
• The fingerprint-region bands at 1260, 1133, and 1027 cm-1 are too nonspecific to confirm whether the heteroatom contribution is mainly C-O, C-N, or another substituted aromatic feature.
• The substitution pattern on the aromatic ring(s) cannot be determined confidently from the present evidence alone.
• It remains uncertain whether the sample is a discrete small molecule, a mixture, or an aromatic polymer/additive-bearing material.

Recommended next steps: Verify whether the sample contains oxygenated functionality by checking for a clear O-H or carbonyl band in a repeat FTIR run collected with improved baseline and full-range coverage. Compare against targeted reference spectra for alkyl-substituted benzenes, aromatic alcohols/ethers, and aromatic amines rather than relying on the current global top hit. Use complementary GC-MS or LC-MS if the sample is extractable, to determine whether it is a single aromatic compound or a mixture. If polymer or coating origin is suspected, collect ATR-FTIR from multiple spots and compare with known styrenic and phenyl-containing material references.
