Properties

Description

Tr-PEG9 is a PEG linker featuring a trityl (Tr) protecting group and a terminal hydroxyl group. The trityl group protects the primary alcohol, offering stability during synthesis, and can be easily removed under mild acidic conditions. The PEG9 chain enhances solubility and hydrophilicity in aqueous media, while the hydroxyl group provides a reactive site for further functionalization.
