Usage And Synthesis

Chemical Properties

clear yellow to amber liquid

Uses

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 benzothiazole2 and 3-(benzothiazol-2-yl)coumarin derivatives. The ternary complexes of copper (II) with salicylidene-2-aminothiophenol (L) and glycine, alanine, valine and histidene amino acids.

Uses

A multifunctional compound which shows antioxidant activity in a skin cell model of UVA-induced stress.

Uses

2-Aminothiophenol was used in one-pot synthesis of stable phosphonium ylides. It was also used in the synthesis of 2-[(2-benzothiazolylmethyl)thio]-benzenamine. It was used to functionalize silver nano particles for biological pH sensing based on surface enhanced Raman scattering.

Definition

ChEBI: 2-aminothiophenol is an aryl thiol that is thiophenol substituted at position 2 by an amino group. It has a role as a plant metabolite. It is a substituted aniline and an aryl thiol.

Synthesis Reference(s)

Journal of the American Chemical Society, 68, p. 1514, 1946 DOI: 10.1021/ja01212a038

General Description

2-Aminothiophenol couples with Amberlite XAD by means of an N=N spacer to prepare a new functionalized resin for on-line preconcentration of copper and cadmium.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion. Moderately flammable. Can react with oxilzing materials. To fight fire, use water, foam, CO2, mist or spray, dry chemical
