Fluorinated aniline derivatives of the general formula I are described ##STR1## in which R.sup.1 represents H or (CH.sub.2).sub.n -X, n is a whole number from 1 to 3, X is H, OH, NH.sub.2, CH.sub.3 CONH, CH.sub.3 SO.sub.2 NH, SO.sub.3 H or ArSO.sub.3 H, Ar is optionally substituted arylene radical, R.sup.1 is alternatively also a --(CH.sub.2).sub.3 -- group, which is bonded to the free o-position next to the N-atom, Y is H, --O--, --NH--, --S-- or a C--C single bond, R.sup.2, in the event that Y=H, is the same as or different from R.sup.1 and means one of the radicals shown for R.sup.1, and in the event that Y is a C--C single bond or --O--, --NH-- or --S--, is an alkylene group having 1 to 3 carbon atoms linked with Y, and R.sup.3 =H, alkyl having 1 to 3 carbon atoms, OCH.sub.3, CH.sub.3 CONH, CO.sub.2 H or SO.sub.3 H. The compounds of formula I form as coupling components together with the conventional color couplers a very sensitive chromogenic system which is suitable for the analytical determination of oxidizing substances, for example for the determination of H.sub.2 O.sub.2 and POD in body fluids.

生物描述如下:其中R.sup.1代表H或(CH.sub.2).sub.n -X,n是1到3之间的整数,X是H、OH、NH.sub.2、CH.sub.3 CONH、CH.sub.3 SO.sub.2 NH、SO.sub.3 H或ArSO.sub.3 H,Ar是可选取代的芳基基团,R.sup.1也可以是与N原子旁边的自由o-位置结合的--(CH.sub.2).sub.3--基团,Y是H、--O--、--NH--、--S--或C--C单键,如果Y=H,则R.sup.2与R.sup.1相同或不同,并表示R.sup.1所示的基团之一,如果Y是C--C单键或--O--、--NH--或--S--,则R.sup.2是与Y连接的具有1到3个碳原子的烷基基团,R.sup.3=H、具有1到3个碳原子的烷基、OCH.sub.3、CH.sub.3 CONH、CO.sub.2 H或SO.sub.3 H。通式I的化合物与传统的显色
偶联剂一起形成了非常敏感的色素系统,适用于氧化物质的分析测定,例如用于体液中H.sub.2 O.sub.2和POD的测定。
