Triphenylmethane dye-type indicators are a class of organic color-change reagents based on triarylmethane or related lactone/quinoid structures. They are widely used in acid-base titration, non-aqueous titration, complexometric titration, protein assays, histological staining, microbiological ...
In life-science experiments, reagents whose names contain “green” are primarily used as acid–base indicators, histology/cytology counterstains and contrast stains, and in selected microbiology and cytology staining workflows. These reagents often sit at critical process nodes: color transitions ...
