4-(Hydroxymethyl)benzoic acid (HMBA Linker) on HypoGel®
HypoGel® is a hydrophilic Gel® type resin which combines high loading and a hydrophilicity between polystyrene and TentaGel®. 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.
