铬连苯三酚红用于络合滴定和分光光度法测定大多数元素。卢加诺夫等提出将它用于分光光度法测定矿石中的铀,此法预先用α-亚硝基-β-萘酚共沉淀分离铀。利用生成金属-有机显色剂-季胺盐三元络合物的反应来提高灵敏度和选择性,季胺盐利用了溴化十六烷基三甲基铵和溴化十六烷基吡啶。在文献中,介绍了铀酰离子与 Chrome pyrogallol red is used for complexometric titration and spectrophotometric determination of most elements. Luganov proposed to use it for the spectrophotometric determination of uranium ore, this method was pre-α-nitroso-β-naphthol co-precipitation of uranium. Sensitization and selectivity are enhanced by reactions that generate metal-organic chromogen-quaternary ammonium salt ternary complexes that utilize cetyltrimethylammonium bromide and cetylpyridinium bromide. In the literature, uranyl ions are introduced
