HypoGel® 400 PHB , 110 - 150 µm

HypoGel® is a hydrophilic Gel® type resin which combines high capacities with good solvent compatibility. Glycol spacers with n = 5 or 10 EO units separate the reactive sites from the polystyrene matrix and modify the hydrophobic properties of the polystyrene backbone. Due to the spacer effect the functional group shows a higher mobility which results in higher kinetic rates and high resolution NMR spectra from immobilized compounds on the bead. The resin is compatible to a wide range of solvents and in contrast to polystyrene even polar solvents like methanol or ethanol can be used. These resins show high loading and a hydrophilicity between polystyrene and TentaGel®.
This resin is recommended for the synthesis of short peptides (10 - 15 residues).
The p-hydroxybenzyl alcohol attached to HypoGel® makes this resin ideal for attaching carboxylic acids for further functionalisation and peptide synthesis. Cleavage conditions are concentrated TFA or TFA/DCM mixtures to provide carboxylic acids, peptides or cyclization-cleavage under acidic or basic conditions.
In this resin the glycol spacer contains 10 EO units which separate the reactive sites from the polystyrene matrix.
