Mordant Brown 33 (3618-62-0)  
MB33 cpd  ·  2,4-diamino-5-(2-hydroxy-5-nitrophenylazo)benzenesulfonic acid sodium salt
Mordant brown 33 (MB33) is 2,4-diamino-5-(2-hydroxy-5-nitrophenylazo) benzene sulfonic acid sodium salt. The UV-Visible spectra of MB33 in all mixtures investigated display three absorption bands in 50% ethanol within all the pH ranges 1.5-13.3 using Thiel buffer the maximum absorption of these bands is located at 438, 453 and a double head band at 410 and 475 nm . The band at 438 nm corresponds to absorption attributed to the cationic form (LH6) of MB33 (whereas L indicates to the parent structure of ligand without hydrogen protons) and disappears at pH > 3.0.
Janus green B (2869-83-2)  
Janus Green B is a basic dye and vital stain used in histology. It is also used to stain mitochondria supravitally, as was introduced by Leonor Michaelis in 1900. The indicator Janus Green B changes colour according to the amount of oxygen present.

Triphenylmethane, or triphenyl methane, is the hydrocarbon with the formula (C6H5)3CH. This colorless solid is soluble in nonpolar organic solvents and not in water. Triphenylmethane is the basic skeleton of many synthetic dyes called triarylmethane dyes, many of them are pH indicators, and some display fluorescence.
