Peptides and other esters can be cleaved with 1-5% TFA in DCM. This property makes it very useful for a high number of applications.
TentaGel® resins consist of low cross-linked polystyrene on which poly(ethylene glycol) with a molecular weight of 1500 Da to 2000 Da is grafted. The PEG spacer is attached to the polymer matrix via an ether bond, which shows high stability towards acid treatment and minimizes PEG leaching. The properties of TentaGel® resins are dominated by PEG, which solubilizes both hydrophobic and hydrophilic compounds. TentaGel® resins are pressure stable and can be used in batch processes as well as under continuous flow conditions.
