FTIR 證據不支持將樣品明確鑑定為 4-methylbenzene-1,3-diamine。譜庫搜尋實際上不匹配,所有主要候選物報告的相似度為零,且沒有直接或相關文獻縮小指定範圍。觀察到的譜帶更符合廣泛的含甲基取代含雜原子有機材料,顯示 C-O 吸收和可能的 N-H 官能團,而非特定的指定化合物。
建議的下一步: Reacquire the FTIR spectrum with full peak intensities and band shapes, especially in the 1800-600 cm-1 fingerprint region, to test whether the 1226/1057 cm-1 pair reflects ether, cyclic acetal, or other C-O functionality. Inspect the 3500-3000 cm-1 region at higher quality to determine whether the 3277 cm-1 band is a sharp amine-type N-H feature or a broader O-H band. Check for additional aromatic ring bands near 1600, 1500, 830-700 cm-1 to assess whether a methyl-substituted aromatic amine remains plausible. If available, confirm with complementary Raman, GC-MS, or NMR analysis to distinguish an oxygen-containing ring system from an aromatic amine or other heteroatom-containing organic component.
