Infrared spectrum comparison chart. Analysis result: heteroatom-containing organic material with possible amine/alcohol character.

The FTIR evidence does not support a firm material identification. The nearest library hit is Poly(ethylenimine),epichlorohydrin modified, but the match confidence is effectively absent and no direct or related literature evidence independently supports that assignment. The observed spectrum is dominated by a broad band near 3321 cm-1, a band near 1025 cm-1, and several weak features in the 1900-2300 cm-1 region, which together are more consistent with a broadly heteroatom-containing organic material, potentially bearing hydrogen-bonded O-H and/or N-H groups, than with a securely identified specific polymer or sulfur heterocycle

Conclusion

heteroatom-containing organic material with possible amine/alcohol character

Conclusion

The top two library candidates are polyamine-related materials: Poly(ethylenimine),epichlorohydrin modified and Poly(ethylenimine).
The observed 3321 cm-1 band is compatible with amine- or alcohol-containing materials.
The 1025 cm-1 band is compatible with C-N or C-O functionality, which is reasonable for polyamine/polyol-like materials among the leading candidates.

การจับคู่หลักของคลังข้อมูล

Poly(ethylenimine),epichlorohydrin modified #7725

Limitations

Evidence that limits the conclusion

All listed library similarities are 0.000, S-O the library search does not provide a reliable direct match.
The library consensus note pointing to sulfur heterocycle / methyl is not convincingly reflected by the observed peak set, which lacks clear characteristic aromatic sulfur-heterocycle evidence.
The observed peak set does not show a distinctive, complete pattern expected to safely confirm the named top candidate.
The broad 3321 cm-1 feature cannot distinguish confidently between O-H-rich and N-H-rich materials.
The weak structure in the 1900-2300 cm-1 region remains ambiguous and may not belong to the principal sample chemistry.
Without stronger fingerprint-region agreement, the present data cannot separate polyamine, polyol, or other heteroatom-containing organic possibilities.
A specific entity-level identification is not supportable from the current FTIR evidence alone.

Recommendation

Suggested next verification

Recollect the FTIR spectrum with atmospheric CO2/H2O background control to check whether features near 2236 and 2334 cm-1 persist.
Obtain a higher-quality fingerprint-region spectrum, especially 1800-700 cm-1, and compare for characteristic amine versus alcohol/polyol band patterns.
Check for complementary evidence by Raman, elemental analysis, or XPS to determine whether nitrogen, sulfur, or chlorine is actually present.
If a poly(ethylenimine)-type material is suspected, verify with wet-chemical amine testing or compare against authenticated PEI and epichlorohydrin-modified PEI reference spectra under the same measurement conditions.
