The present invention provides a colorimetric process for the detection of an oxidative coupling reaction in which a coupling component is reacted with a developer component in the presence of an oxidation agent to give a colored material, wherein, as coupling component, there is used a compound of the general formula: ##STR1## in which X is a bromine or chlorine atom, n is 1, 2 or 3, Y is COOR, CONRR', SO.sub.3 R, SO.sub.2 NRR', OR, NRR' or NRR'R".sym. and R, R' and R", independently of one another, are hydrogen atoms or C.sub.1 -C.sub.3 -alkyl radicals. The present invention also provides a reagent which contains the above compound, as well as new substituted phenols and a process for the preparation thereof.
本发明提供了一种用于检测氧化偶联反应的比色过程,其中在氧化剂存在下,偶联组分与显色剂组分发生反应,形成一种有色物质,其中作为偶联组分使用具有一般式的化合物:##STR1## 其中X是溴或氯原子,n为1、2或3,Y为COOR、CONRR'、SO.sub.3R、SO.sub.2NRR'、OR、NRR'或NRR'R",R、R'和R"独立地为氢原子或C.sub.1-C.sub.3-烷基基团。本发明还提供了一种含有上述化合物的试剂,以及新的取代酚和其制备方法。
