Description

Chemical Structure

 

Product Description of Calixarenes
WSC is a water soluble carbodiimide. It is also soluble in alcohol, acetone, chloroform, dioxane, and DMF. WSC is used as a condensing agent for peptide syntheses. WSC and its urea form can be easily removed after the reaction due to their high water solubility. WSC, EDC, EDAC, EDCI, and ethyl-CDI are the same reagent.
