Descrição geral

Potassium acetate (KOAc) is the potassium salt of acetic acid. It is commonly used as a base in organic synthesis for various reactions, which include Lossen rearrangement of hydroxamic acids, E2 eliminations, deprotonations of alcohols, transition metal-catalyzed reactions, and fragmentation reactions. Additionally, KOAc is also used as a nucleophilic catalyst for addition and polymerization reactions.

Aplicação

Potassium acetate can be used as an activating agent for the activation of carbon materials.

Características e benefícios

  • Increased efficiency – Eliminates time and effort of loosening hardened powders      
  • Safety – Eliminates tools of force used to break up clumps
  • Ecology – Reduces waste as it does not stick to the packaging
  • Economy – Faster preparation and solvation increase productivity and reduce costs     
  • Assured Quality – Excellent, expert-tested quality with no anti-caking agents      
  • Flexible volumes – Available from research amounts to scale-up quantities

Stable intronic sequence RNAs (sisRNAs) have been found in Xenopus tropicalis, human cell lines, and Epstein-Barr virus; however, the biological significance of sisRNAs remains poorly understood. We identify sisRNAs in Drosophila melanogaster by deep sequencing, reverse transcription polymerase chain reaction
