A compound of the formula:
wherein X is a non-chromophoric bridging group which provides at least three single covalent bonds between Ring B and the group R;
R is a group containing a reactive halogen atom; & each A independently is H or an acidic group;
provided that the molecule contains sufficient acidic groups to render it water soluble and that when X provides only 3 covalent bonds between Ring B and R, the latter is not a chlorodifluoropyrimidyl group, which is suitable for the preparation of a protein adsorbent or precipitant for use in the separation of mixtures of proteins.
一种式中的化合物:其中 X 是非色素桥基,在环 B 和基团 R 之间提供至少三个单共价键;R 是含有活性卤原子的基团;& 每个 A 独立地是 H 或酸性基团;条件是分子中含有足够的酸性基团使其可溶于
水,并且当 X 在环 B 和 R 之间只提供 3 个共价键时,后者不是
氯二
氟嘧啶基团,该化合物适用于制备用于分离蛋白质混合物的蛋白质吸附剂或沉淀剂。
