• Top library match: 1-Bromodocosane #114

• All listed library similarities are 0.000, S-O the reference library comparison does not provide a reliable compound-level match.
• No related-literature evidence was recovered to reinforce a brominated alkane assignment.
• The reported spectrum lacks additional distinguishing bands needed to support a specific halogenated alkane rather than a more general hydrocarbon-like material.
• FTIR here supports alkyl-chain chemistry but does not establish whether the sample is a pure alkane, a haloalkane, or part of a more complex organic mixture.
• A bromine-containing assignment remains only a weak possibility from the library name, not from confirmed spectral evidence.
• The limited number of reported peaks prevents a narrower and more secure material conclusion.

Recommended next steps: Re-acquire the FTIR spectrum over the full mid-IR range with improved signal quality and complete peak listing, especially in the fingerprint region below 1500 cm⁻¹. Check for additional methylene rocking and fingerprint features expected for long, linear alkyl chains to strengthen or weaken the long-chain assignment. Use a complementary method that can test for bromine directly, such as XRF, EDS, or mass spectrometry, if a brominated material is suspected. If the sample may be a mixture or residue, compare extracted fractions separately to determine whether the alkyl-chain signal comes from a single compound or a blended material.
