General description
Thymol Blue is a pH indicator with visual transition intervals of pH 1.2 (red) to pH 2.8 (yellow), and pH 8.0 (yellow) to pH 9.2 (blue).
Application
Thymol Blue sodium salt was used to indicate the changes in pH to reflect ionization in multi-component drug formulations.

Sulfobromophthalein electrogenic uptake into rat liver plasma membrane vesicles was shown to admit only the quinoid, trivalent anion. The minimum requirement for this electrogenic process has been investigated in rat liver plasma membrane vesicles by using Thymol blue, a pH-indicator

With most existing methods, transverse dispersion coefficients are difficult to determine. We present a new, simple, and robust approach based on steady-state transport of a reacting agent, introduced over a certain height into the porous medium of interest. The agent

The standard assay for iodoperoxidase activity is based on the spectrophotometric detection of triiodide formed during the enzymatic reaction. However, chemical instability of I3- has limited the method to high iodide concentrations and acidic conditions. Here we describe a simple
