General description

2-Aminothiophenol is an organosulfur compound used in the synthesis of urea derivatives.

Application

2-Aminothiophenol was used in the synthesis of 1,5-benzothiazepines derivatives by reacting with 1,3-diphenylpropenone derivatives and using aluminosilicate solid catalysts. It was also used in the synthesis of benzothiazole and 3-(benzothiazol-2-yl)coumarin derivatives.

Novel ESIPT inspired benzimidazole, benzoxazole and benzothiazole were synthesized from 2,4-dihydroxy benzoic acid and 1,2-phenelenediamine, 2-aminophenol, and 2-aminothiophenol respectively. The synthesized 2-(2',4'-dihydroxyphenyl) benzimidazole, benzoxazole and benzothiazole are fluorescent and the emission characteristic are very sensitive to the micro-environment. They show

1,5-Benzothiazepines derivatives were obtained first by starting from 1,3-diphenylpropenone derivatives (chalcones) and 2-aminothiophenol by using aluminosilicate solid catalysts. However, diffusional limitations and the strong adsorption of products on the catalyst are deleterious for catalyst activity and life. Then a structured

Two different types of fluorescent materials containing benzothiazolyl moiety, 2-(benzothiazol-2-yl)phenol derivatives and 3-(benzothiazol-2-yl)coumarin derivatives, were synthesized synchronously using ethyl cyanoacetate, appropriate aromatic aldehyde and 2-aminothiophenol as the starting materials under the catalysis of benzoic acid by one-pot reaction. This method

We report pH sensing for biological applications based on surface enhanced Raman scattering (SERS) from silver nanoparticles functionalized with 2-aminothiophenol (2-aminobenzenethiol, 2-ABT). pH-dependent SERS spectra of the attached 2-ABT molecules enable one to sense the pH over the range of
