Compounds of general formula I are used as labels in an electrochemical assay: (I) in which: Fc and Fc′ are substituted or unsubstituted ferrocenyl moieties, X is a C1 to C6 alkylene chain which is optionally interrupted by —O— or —NH—; Y is a C1 to C6 alkylene chain which is optionally interrupted by —O— or —NH—; Z is a C1 to C12 alkylene chain which may optionally be substituted and/or may optionally be interrupted by —O—, —S—, cycloalkyl, —CO—, —CON R1—, —NR1CO— or —NR1— in which R1 represents hydrogen or C1 to C4 alkyl; and R is a linker group. Compounds I are used to make labelled substrates, as well as functionalised compounds for making the labelled substrates.
通式I的化合物被用作电
化学测定中的标记物:其中:Fc和Fc'是取代或未取代的
二茂铁基团,X是C1到C6的烷基链,可以被—O—或—NH—中断;Y是C1到C6的烷基链,可以被—O—或—NH—中断;Z是C1到C12的烷基链,可以选择性地被取代和/或可以被—O—、—S—、环烷基、—CO—、—CON R1—、—NR1CO—或—NR1—中断,在其中R1代表氢或C1到C4的烷基;而R是连接基团。化合物I被用于制备标记底物,以及用于制备标记底物的功能化化合物。
