| 2-Aminobenzenethiol Usage And Synthesis |
| Chemical Properties | clear yellow to amber liquid | | Uses | A multifunctional compound which shows antioxidant activity in a skin cell model of UVA-induced stress. | | 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 | 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. | | 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 |
