Infrared spectrum comparison chart. Analysis result: nitrogen-containing organic material with possible nitrile and N-H functionality.

The current FTIR evidence does not support a firm identification as Boric acid despite that library entry appearing first, because the library match quality is effectively absent and the observed bands are not characteristic of a simple boric acid spectrum. Instead, the sample is more cautiously described as a nitrogen-containing organic material, with a strong possibility of nitrile functionality and at least one N-H or hydrogen-bonded O-H containing group

Conclusion

nitrogen-containing organic material with possible nitrile and N-H functionality

General assessment

#35827 Initial rank 1 Current rank 1 Library lead match 0.0%

Conclusion

The 2260 cm-1 band supports a nitrile-region assignment.
The 3466 and 3163 cm-1 bands support the presence of N-H and/or hydrogen-bonded O-H stretching.
The library consensus mentions methyl / n h, which is at least broadly consistent with organic nitrogen-containing material.

Main limitation

The leading library hit Boric acid has a similarity of 0.000, so the retrieval does not provide positive identification support.

Support

Evidence supporting the conclusion

Only sample-relevant statements that support the present conclusion are shown here.

The current FTIR evidence does not support a firm identification as Boric acid despite that library entry appearing first, because the library match quality is effectively absent and the observed bands are not characteristic of a simple boric acid spectrum. Instead, the sample is more cautiously described as a nitrogen-containing organic material, with a strong possibility of nitrile functionality and at least one N-H or hydrogen-bonded O-H containing group.
The 2260 cm-1 band supports a nitrile-region assignment.
The 3466 and 3163 cm-1 bands support the presence of N-H and/or hydrogen-bonded O-H stretching.
The library consensus mentions methyl / n h, which is at least broadly consistent with organic nitrogen-containing material.
Several leading library candidates contain nitrogen- or carbonyl-bearing organic motifs, which is directionally consistent with the observed non-mineral-like spectrum.
The observed spectrum is defined here by bands near 3466 and 3163 cm-1, a strong feature near 2260 cm-1, and additional bands near 1448 and 866 cm-1.
A band near 2260 cm-1 is most consistent with a nitrile-region absorption and is not expected to support a boric acid assignment.
Bands at 3466 and 3163 cm-1 are consistent with N-H stretching or hydrogen-bonded O-H stretching, which agrees better with a nitrogen-containing organic direction than with a simple inorganic boric acid assignment.
The Top-15 library pattern is highly mixed and low-quality, including boric acid, acetate salts, amide-containing polymers, acetamide, and nitrile-containing polymer entries, so it supports only a broad heteroatom-containing organic direction rather than a specific compound.
Among the broader library clues, repeated appearance of amide- or nitrogen-bearing materials is more compatible with the observed high-wavenumber bands than a clean boric acid match.

Limitations

Evidence that limits the conclusion

The leading library hit Boric acid has a similarity of 0.000, so the retrieval does not provide positive identification support.
The strong 2260 cm-1 band is a major limitation for a boric acid conclusion and instead points toward a different functional class.
The Top-15 library candidates are chemically inconsistent with one another, which limits confidence in any narrow material assignment.
The available peak list is sparse, so the presence or absence of key companion bands for nitriles, amides, borates, or carboxylates cannot be checked fully.
The high-wavenumber bands could reflect N-H, O-H, or mixed hydrogen-bonded contributions, so the heteroatom functionality is not uniquely resolved.
Without clearer fingerprint-region structure, the sample cannot be narrowed reliably to a specific nitrile, amide, polymer, salt, or small molecule.

Recommendation

Suggested next verification

Reacquire the FTIR spectrum with full fingerprint-region quality and confirm whether additional bands appear near 1700-1600 cm-1 and 1300-1000 cm-1 to distinguish amide, carboxylate, borate, and other heteroatom-containing groups.
Inspect the 2260 cm-1 feature at higher signal-to-noise to confirm whether it is a true characteristic nitrile band rather than an artifact or atmospheric contribution.
If this sample may be polymeric, compare against reference spectra of nitrile-containing and amide-containing materials, especially benzonitrile-like or acrylamide-related materials.
Use complementary elemental screening such as EDS, XRF, or combustion/CHN analysis to test whether boron is actually present; absence of boron would further rule out the library-leading boric acid suggestion.
