FTIR证据不支持将样品确定为4-甲基苯-1,3-二胺。谱库搜索实际上不匹配,所有主要候选物报告相似度为零,且无直接或相关文献缩小归属。观察到的谱带更符合广泛的甲基取代含杂原子有机材料,显示C-O吸收和可能的N-H官能团,而非特定命名化合物。
推荐的后续步骤: 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.
