Rink Acid resin (100-200 mesh), NovaBiochem; 1g
An extremely versatile, acid-labile resin for the solid phase immobilization of carboxylic acids, alcohols, phenols and amines, imidazoles and hydroxylamines. Release of these functionalities is generally achieved using 1-50% TFA in DCM containing 5% TIS, although carboxylic acids can also be cleaved from this support with AcOH/TFE/DCM, 0.5% TFA in DCM, or HFIP in DCM.
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 trialkylsilanes to the cleavage mixture. Color (visual): white to pale yellow to beige.
