Application

Potassium selenocyanate can be used as a:
  • Redox-active electrolyte to enhance the performance of carbon-based supercapacitors.
  • Starting material for the one-pot stereoselective synthesis of alkyl styryl selenides.
  • Precursor to synthesize Cu and Ni complexes with antioxidant/anti-inflammatory activities.
  • Selenylating agent to prepare stereoselective selenoglycosides and selenium-linked disaccharides.

General description

Potassium selenocyanate is a crystalline solid and a reagent for the conversion of alkyl halides to nitriles, and the production of pharmaceutical intermediates. It also finds application in the field of energy storage devices.
