Description and Uses

Hydroxy-PEG10-t-butyl ester is a PEG linker containing a hydroxyl group with a t-butyl ester. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The t-butyl protected carboxyl group can be deprotected under acidic conditions.

Hydroxy-PEG10-Boc is extacted from patent CN108707228 (example 0024)[1]. Hydroxy-PEG10-Boc is a uncleavable ADC linker used in the synthesis of antibody-drug conjugates (ADCs). Hydroxy-PEG10-Boc can be conjugated to Paclitaxel (HY-B0015) or docetaxel (HY-B0011)[2].
