Beschreibung

1,2-Ethanedithiol is used as a reagent in organic synthesis to convert carbonyl compounds to thioacetals (1,3-dithiolanes). It replaces the toxic reagent arsenic tirchloride, which is involved in the synthesis of membrane-permeant fluorogenic biarsenicals from precursor dyes fluorescein and resorufin. It acts bidendate ligand to form complexes with metal ions.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Anwendungen
1,2-Ethandithiol wird als Reagenz bei der organischen Synthese von Thioacetalen (1,3-Dithiolanen) aus Carbonylverbindungen verwendet. Ersetzt das toxische Reagenz Arsentrichlorid, das membrandurchdringende fluoreszierende Arsenverbindungen aus Vorläuferfarbstoffen Fluorescein und Resorufin bildet. Bildet als bidendater Ligand Komplexe mit Metallionen.

Löslichkeit
Mischbar mit Ethanol, Aceton, Ether und Benzol. Leicht mit Wasser mischbar.

Hinweise
Luftempfindlich. Von Zündquellen fernhalten. Nicht kompatibel mit Alkalimetallen. Einatmen von Dämpfen vermeiden.
