O-(2-AMINOETHYL)-O-(2-(BOC-AMINO)ETHYL)OCTAETHYLENE GLYCOL Chemical Properties,Uses,Production

Description

t-Boc-N-amido-PEG9-amine is a monodisperse PEG reagent containing an amino group and Boc-protected amino group. The hydrophilic PEG spacer increases solubility in aqueous media. The Boc group can be deprotected under mild acidic conditions to form the free amine.

Uses

Boc-amido-PEG9-amine is a PEG-based PROTAC linker that can be used in the synthesis of PROTACs[1].

General Description

Our highly purified mono-protected homobifunctional polyethylene glycols display oligomer purities of more than 90%. This extremely narrow distribution of oligomers ensures homogeneous products in many applications such as conjugation reactions or introduction of solubilizing units or spacers.

reaction suitability

reagent type: cross-linking reagent
