The invention provides new redox indicators and uses for these redox compounds (I): ##STR1## Wherein X is oxygen or sulphur, R.sub.1 is julolidine or tetrahydroquinoline, which can carry an alkyl radical on the nitrogen atom which, in turn, can be substituted by a sulphuric, phosphonic or carboxylic acid residues, or is (II); wherein R.sub.4 is hydroxyl or a mono- or dialkylated amino group, R.sub.5 and R.sub.6, which can be the same or different, are hydrogen, alkyl or alkoxy, R.sub.2 is hydrogen or alkyl, julolidine or tetrahydroquinoline, which can carry an alkyl on the nitrogen atom which alkyl can be substituted by sulphuric, phosphonic or carboxylic acids, or is III; wherein R.sub.5 and R.sub.6 are the same as in R.sub.1 and R'.sub.4 is hydroxyl, an amino or a mono-or dialkylated amino group, whereby the alkyl radicals can be substituted one or more times by hydroxyl, alkoxy, halogen, morpholine or a sulphuric, carboxylic or phosphonic acid residue, which acids can also be esterified, and R.sub.3 is the same as R.sub.2 or is an alkyl substituted by hydroxyl, alkoxy, dialkylamino or phenyl, or is cycloalkyl, phenyl or pyridyl; as well as the salts thereof.
这项发明提供了新的氧化还原指示剂以及这些氧化还原化合物的用途(I):其中X为氧或硫,R.sub.1为茱萸啉或四氢喹啉,氮原子上可以携带一个烷基基团,该基团又可以被硫酸、磷酸或羧酸残基取代,或为(II);其中R.sub.4为羟基或单烷基或二烷基氨基,R.sub.5和R.sub.6可以相同也可以不同,为氢、烷基或烷氧基,R.sub.2为氢或烷基,茱萸啉或四氢喹啉,氮原子上可以携带一个烷基,该烷基可以被硫酸、磷酸或羧酸取代,或为III;其中R.sub.5和R.sub.6与R.sub.1相同,R'.sub.4为羟基、氨基或单烷基或二烷基氨基,烷基基团可以被羟基、烷氧基、卤素、吗啉或硫酸、羧酸或磷酸残基取代一次或多次,这些酸也可以酯化,R.sub.3与R.sub.2相同或为烷基,被羟基、烷氧基、二烷基氨基或苯基取代,或为环烷基、苯基或吡啶基;以及其盐。
