一般描述
o-Toluidine belongs to the class of monocyclic aromatic amines, which are of research and industrial importance. It can be used as a derivatization agent for the resolution of analytes by the formation of chromophores, which can be visualized by UV radiation or fluorescence.
应用
o-Toluidine may be used as a TLC Visualization (Staining) Reagent for the detection of reducing sugars in protein hydrolysates by using high-performance thin-layer chromatography (HPTLC) coupled with UV diffuse reflectance scanning densitometry.

Electrochemical oxidation of O-toluidine (OT) was studied by galvanostatic electrolysis using lead dioxide (PbO2) and boron-doped diamond (BDD) as anodes. The influence of operating parameters, such as current density, initial concentration of OT and temperature was investigated. Measurements of chemical

The rotationally resolved spectrum of the o-toluidine S(1)<-- S(0) origin was measured using laser induced fluorescence spectroscopy. From the resulting spectrum torsional barriers to internal rotation of the methyl group were derived, which resulted in S(0) state values of V(3)
