Descrizione generale

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.

Applicazioni

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.

The electrochemical synthesis and characterization of a copolymer, poly(o-toluidine-co-o-aminophenol), were conducted using in situ piezoelectric FTIR spectroelectrochemistry. The monomer feed ratio strongly affects the copolymerization rate and the properties of the copolymer during the electrosynthesis in 0.5M H(2)SO(4) aqueous solution.
