Rink Amide resin (100-200 mesh)

An excellent support for the Fmoc SPPS of peptide amides. This resin is more acid-sensitive than Rink Amide AM and Rink Amide MBHA resins. Cleavage with high concentrations of TFA can lead to the breakdown of the linker, with the concomitant formation of by-products that can not be removed by simple washes. These problems appear to be minimized through the use of low TFA concentrations or by the addition of trialkyl silanes to the cleavage mixture.
