说明

General description

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.

Application

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.

Structure and internal rotation in the S(0) and S(1) states of o-toluidine studied by high resolution UV spectroscopy.

Ivo Kalkman et al.

Physical chemistry chemical physics : PCCP, 11(21), 4311-4318 (2009-05-22)

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)
