• Top library match: 1-Chloro-2-iodobenzene #113

• 1-Chloro-2-iodobenzene does not contain an O-H or N-H group, S-O the observed 3288 cm-1 band argues against that specific assignment.
• The current spectrum does not provide distinctive support for the exact halogen pattern implied by 1-Chloro-2-iodobenzene.
• The peak list is sparse, S-O important confirming or excluding bands may be missing from the present interpretation.
• The 3288 cm-1 feature could reflect O-H, N-H, or possibly moisture contribution; without band shape and full-spectrum context its origin remains uncertain.
• Fingerprint-region bands at 1008, 1200, and 1330 cm-1 are not sufficiently distinctive on their own to choose among alcohol, amine, ether, phenolic, or other substituted aromatic possibilities.
• Because the library match quality is effectively non-discriminating, the named library compound should be treated only as the nearest database entry, not as a supported identification.

Recommended next steps: Reacquire the full FTIR spectrum with attention to band shape and intensity in the 3600-3000 cm-1 region to determine whether the 3288 cm-1 feature is a true O-H/N-H band or residual moisture. Inspect the 1800-600 cm-1 region for confirming aromatic substitution features and for bands that would distinguish phenol/alcohol, amine, ether, nitro, or sulfonyl functionality. If halogenated aromatic identity is still being considered, confirm by GC-MS or LC-MS because FTIR alone is not securely supporting the specific chloro-iodobenzene assignment here. If the sample is expected to be a solid or formulated material, compare replicate spectra after drying to see whether the 3288 cm-1 band persists.
