설명

일반 설명

1,2-Ethanedithiol (1,2-Dimercaptoethane, Dithioglycol, Ethylene mercaptan) is an organo sulfur compound. It affords monomeric, dimeric and polymeric complexes on reaction with Pt(PPh₃)₄, Pd(PPh₃)₄ and Ni(PPh₃)₄.[1] It has been synthesized by refluxing 1,2-dichloroethane with thiourea in ethanol.[2]

애플리케이션

1,2-Ethanedithiol may be used in the following studies:

• Synthesis of membrane-permeant, fluorogenic biarsenicals.[3]
• Development of microarrays of protein interaction and quantifying the domain-peptide interactions in high throughput using fluorescently labeled synthetic peptides.[4]
• As insolubilizing agent in a study to evaluate the structural, optical, and electrical properties of high-quality films of PbSe nanocrystals fabricated by a layer-by-layer (LbL) dip-coating method.[5]
• Quantitation of the extent of protein phosphorylation using a phosphoprotein isotope-coded affinity tag (PhIAT).[6]
