The spectrum is best described conservatively as a long-chain aliphatic hydrocarbon-like material. The observed bands at about 2918 and 2849 cm⁻¹ are characteristic of saturated alkyl C-H stretching, and the band near 1462 cm⁻¹ is consistent with methylene bending from a hydrocarbon chain. Although the nearest library name is 1-Bromodocosane, the match confidence is effectively absent and there is no direct or literature evidence confirming a specific brominated compound. A narrow assignment to that exact substance is therefore not chemically supportable from the present FTIR evidence alone
