Tr-PEG2-OH is a trityl ether protected PEG chain. The trityl ether groups serve as protective moieties, shielding the hydroxyl groups of PEG from undesired reactions during synthesis and handling. These protective groups can be selectively removed under mildly acidic conditions or via hydrogenolysis, exposing the hydroxyl groups for further conjugation reactions.

The hydrophilic nature of the PEG linker enhances the water solubility of Tr-PEG2-OH in aqueous media, making it suitable for use in biological and biomedical applications. This increased solubility allows for the facile manipulation and processing of the compound in aqueous environments.
