偶氮氯膦Ⅲ

易溶于水，微溶于醇，不溶于醚、氯仿和四氯化碳。摩尔消光等比系数为74，500～75，500，具有比偶氮胂Ⅰ更高的络合性能。 Chlorophosphonazo III is a highly sensitive reagent and can be used for the spectrophotometric determination of zirconium, titanium, thorium and scandium. It also finds application as an extractant, along with 1-butanol as solvent, for determination of micromolar concentrations of Nd(III), Th(IV) and U(VI) in brine. Above all that, it has two long wavelength maxima, one at 620 nm and one at 680 nm用于分光光度法测定碱土金属试剂，测定铀和锶，可在不同条件下与钙、钡、镁、铜、锌、铅、铁、钴、镍、铍、铝、钇、钍、铈和铵等形成有色化合物。
