该光谱最佳解释为2‑二乙氧基磷酰基乙酸乙酯(一种膦酸酯),基于较高的谱库相似度(0.928)以及与多个文献报道的膦酸酯谱带的紧密一致性。
推荐的后续步骤: Compare the sample spectrum with an authentic ethyl 2‑diethoxyphosphorylacetate standard to confirm the full band profile. Acquire ³¹P NMR or Raman data to unambiguously identify the phosphonate environment and rule out overlapping ester mixtures. Perform thermal analysis (TGA/DSC) to assess sample purity and detect any inorganic contaminants that could account for the 668 and 1407 cm⁻¹ peaks.
