Hydroxy-PEG3-t-butylester Chemical Properties,Usage,Production

Description

Hydroxy-PEG2-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.

Uses

Hydroxy-PEG2-(CH2)2-Boc is an ADC linker for the synthesis of antibody drug conjugates (ADC), Hydroxy-PEG2-(CH2)2-Boc is derived from patent WO2004008101A2 (compound 196). Hydroxy-PEG2-(CH2)2-Boc can also be used as a PROTAC linker for PROTAC synthesis.

in vitro

ADCs are comprised of an antibody to which is attached an ADC cytotoxin through an ADC linker.
