摘要：
2-Hydrazono-4,6-dinitrobenzthiazolones of the formula ##STR1## in which X.sub.1 represents hydrogen, C.sub.1 -C.sub.4 -alkyl, C.sub.1 -C.sub.4 -hydroxyalkyl, C.sub.1 -C.sub.4 -sulphoalkyl or C.sub.1 -C.sub.4 -sulphatoalkyl, andX.sub.2 represents hydrogen or --SO.sub.2 X.sub.3, whereX.sub.3 may represent hydrogen, C.sub.1 -C.sub.8 -alkyl or optionally substituted aryl andX.sub.1 also represents a double bond between the cyclic nitrogen atom and the carbon atom 2 according to the formula II below: ##STR2## where X.sub.2 has the meaning specified under the above formula. These hydrazones may be employed in the preparation of azo dyestuffs and as color formers for detecting of biological substances, and in the determination of H.sub.2 O.sub.2.
