A compound containing the -PO3H2 group (phosphoric acid, one of its monoesters, or an alkylphosphonic acid) may be rapidly assayed by the decrease it produces in the absorbance at 450 nm of a buffered acidic solution of Fe3+ and N(-3) [corrected]. The method has been used to follow chromatograms of sugar phosphates and their phosphonomethyl analogues.
含有 -PO₃H₂基团的化合物（磷酸、其单酯之一或烷基膦酸）可通过其在Fe³⁺和N(-3)的缓冲酸性溶液在450nm处吸光度的降低来快速测定[校正后]。该方法已用于跟踪糖磷酸盐及其膦酰甲基类似物的色谱图。
