FTIR图谱与含强酯羰基和多个C–O键的含氧脂肪族物质最为一致,这大致符合乙酸酯类醚/酯溶剂或相关含氧有机物。谱库中最接近的命名匹配是乙酸1-甲氧基丙-2-基酯,但检索置信度实际上为零,且没有直接的文献或参考确认,因此化学上最安全的结论是更广泛的含氧酯/醚方向,而非确定的化合物级别鉴定。
推荐的后续步骤: Recollect the FTIR spectrum with background control and confirm whether the 2280 cm-1 band persists; if it disappears, it may be atmospheric or instrumental rather than sample-derived. Check for additional ester-characteristic fingerprint detail in a higher-quality spectrum, especially relative intensities in the 1250–1000 cm-1 region, to compare against 1-methoxypropan-2-yl acetate and other alkoxy acetate references. Use GC-MS if the sample is volatile; that would directly test whether 1-methoxypropan-2-yl acetate or another glycol-ether acetate is present. If liquid, compare boiling range or retention behavior against common acetate solvents such as 1-methoxypropan-2-yl acetate, 2-ethoxyethyl acetate, and related alkoxy acetates.
