CAS number：51550-25-5 molecular formula：C20H10N2Na4O15S4
为H酸与变色酸的偶氮化合物，由二者偶合制得。易溶于水，在碱性介质中稳定。PH值9.2～10.9时色泽由红变紫。 测定铍的特效灵敏试剂，它能在PH值12～13.2时与铍呈现乳浊色，很多离子都不影响，三价铁可用维生素C还原，钴、镍、镁、钙等可用EDTA掩蔽。 Beryllon II is an organic azo dye used as a voltammetric probe for protein determination due to its ability to form a protein supermolecular complex.
